The need of finding a new way of working the coal mines of England, and of marketing the coal, which had been such an important factor in the development of the steam-engine, was a scarcely less important factor in the building of the earliest practical railway locomotive. The coal had to be hauled from the pit of the colliery to the shipping place. It was carried in cars that were pushed or pulled over a rude line of wooden or iron rails. But it was evident from the time when James Watt began to build his steam-engines to lift the coal from the mine that men of inventive minds would soon seek to send the cars over the level ground by the same power. We owe the railroad chiefly to the needs of the north of England, and there we find the real birth of the locomotive.
About the beginning of the nineteenth century a number of men in England were experimenting with new means of locomotion, both for merchandise and for passengers. Their projects varied from cars running on wheels and drawn by horses to carriages propelled by small stationary steam-engines, placed at short distances from each other along the road. In 1802 Richard Trevethick, a captain in a Cornish tin-mine, took out a patent for a steam-carriage. The machine he built looked like an ordinary stage-coach on four wheels. It had one horizontal cylinder, which was placed in the rear of the hind axle, together with the boiler and the furnace-box. The motion of the piston was carried to a separate crank-axle, and that in turn gave the motion to the axle of the driving-wheel. This was in itself a great invention, being the first really successful high-pressure engine that was built on the principle of moving a piston by the elasticity of steam against only the pressure of the air. The steam was admitted from the boiler under the piston that moved in a cylinder, and forced it upward. When the motion had reached its limit, the communication between the piston and the under side of the cylinder was shut off, and the steam escaped into the atmosphere. Then a passage was opened between the boiler and the upper end of the piston, which was consequently pushed downward, and then the steam was again allowed to escape. As a result the power of the engine was equal to the difference between the atmosphere’s pressure and the elastic force of the steam in the boiler.
This steam-carriage of Trevethick was fairly successful, and created a great sensation in that part of Cornwall where it was built. He decided to take it to London, and drove it himself to Plymouth, from which port it was to be carried by sea. On the road it caused amazement and consternation, and won the name of Captain Trevethick’s dragon. He exhibited it in London, but after a short time gave up driving it, believing that the roads of England were too badly built to make the use of a steam-carriage feasible.
Other men were working on similar lines. Among them was the owner of a colliery in the north named Blackett, who built a number of engines for propelling coal-cars and used them at his mines. But these were very clumsy and heavy, moved slowly, and had to be continually repaired at considerable expense, so that other miners, after examining Blackett’s engines, decided they were not worth the cost of manufacture. To make the steam-carriage really serviceable it must be more efficient and reliable.
Meantime a young man named George Stephenson, who was working at a coal mine at Killingworth, seven miles north of Newcastle, was studying out a new plan of locomotive. His father had been a fireman in a colliery at Wylam, a village near Newcastle, and there the son George was born on June 9, 1781. He had lived the life of the other boys of the village, had been a herd-boy to care for a neighbor’s cows, had been a “picker” in the colliery, and separated stones and dross from the coal, had risen to assistant fireman, then fireman, then engineman. He was strong and vigorous, fond of outdoor sports, and also considerable of a student. In time he moved to Willington Quay, a village on the River Tyne, where coal was shipped to London. Here he married, and made his home in a small cottage near the quay. He was in charge of a fixed engine on Willington Ballast Hill that drew the trains of laden coal-cars up the incline.
After he had worked for three years at Willington he was induced to take the position of brakesman of the engine at the West Moor Colliery at Killingworth. He had only been settled in his new place a short time when his wife died, leaving him with a son Robert. Stephenson thenceforth threw himself into his work harder than ever, studying with his son as the boy grew older, and spending a great deal of time over his plans for a steam-engine that should move the coal-cars. He knew the needs of the colliery perfectly, had acquired a good knowledge of mechanics, and proposed to put his knowledge to account.
He had already, as engine-wright of the Killingworth Colliery, applied the surplus power of a pumping steam-engine to the work of drawing coal from the deeper workings of the mine, thereby saving a great amount of manual and horse labor. When the coal was drawn up it had to be transported to the quays along the Tyne, and to simplify this Stephenson laid down inclined planes so that a train of full wagons moving down the incline was able to draw up another train of empty wagons. But this would only work over a short distance, and was in itself a small saving in effort.
The engines that Mr. Blackett had built, using Trevethick’s model as a basis, were working daily near the Killingworth Colliery, and Stephenson frequently went over to see them. He studied Mr. Blackett’s latest locomotive, nicknamed “Black Billy,” with the greatest care, and then told his friend Jonathan Foster that he was convinced that he could build a better engine than Trevethick’s, one that would work more effectively and cheaply and draw a train of cars more steadily.
He also had the advantage of seeing other primitive locomotives that were being tried at different places near Newcastle. One of these, known as Blenkinsop’s Leeds engine, ran on a tramway, and would draw sixteen wagons with a weight of seventy tons at the rate of about three miles an hour. But the Blenkinsop engine was found to be very unsteady, and tore up the tram-rails, and when its boiler blew up the owner decided that the engine was not worth the cost of repair. Stephenson, however, drew some useful points from it, as well as from each of the other models he saw, and proposed to himself to follow Watt’s example in constructing his steam-engine, namely, to combine the plans and discoveries of other inventors in a machine of his own, and so achieve a more complete success.
Stephenson was now very well regarded at the colliery for the improvements he had made there. He brought the matter of building a new “Traveling Engine,” as he called it, to the attention of the lessees of the mine in 1813. Lord Ravensworth, the principal partner, formed a favorable opinion of Stephenson’s plans, and agreed to supply him with the funds necessary to build a locomotive.
With his support Stephenson went to work to choose his tools and workmen. He had to devise and make many of the tools he needed, and to train his men specially for this business. He built his first engine in the workshops at the West Moor Mine. It followed to some extent the model of Blenkinsop’s engine. It had a cylindrical boiler, eight feet long and thirty-four inches in diameter, with an internal flue tube passing through it. The engine had two vertical cylinders and worked the propelling gear with cross-heads and connecting-rods. The power of the two cylinders was carried by means of spur-wheels, which continued the motive power to the wheels that supported the engine on the rails. The engine was simply mounted on a wooden frame that was supported on four wheels. These wheels were smooth, as Stephenson was convinced that smooth wheels would run properly on an edge-rail.
This engine, christened the “Blutcher,” and taking about ten months to build, was tried on the Killingworth Railway on July 25, 1814. It proved to be the most successful working engine that had yet been built, and would pull eight loaded wagons of about thirty tons’ weight up a slight grade at the rate of four miles an hour. For some time it was used daily at the colliery.
But the “Blutcher” was after all a very clumsy machine. The engine had no springs, and its movement was a series of jolts, that injured the rails and shook the machinery apart. The important parts of the machinery were huddled together, and caused friction, and the cog-wheels soon became badly worn. Moreover the engine moved scarcely faster than a horse’s walk, and the expense of running it was very little less than the cost of horse-power. Stephenson saw that he must in some way increase the power of his engine if he was to provide a new motive power for the mines.
In this first engine the steam had been allowed to escape into the air with a loud, hissing noise, which frightened horses and cattle, and was generally regarded as a nuisance. Stephenson thought that if he could carry this steam, after it had done its work in the cylinders, into the chimney by means of a small pipe, and allow it to escape in a vertical direction, its velocity would be added to the smoke from the fire, or the rising current of air in the chimney, and would in that way increase the draught, and as a result the intensity of combustion in the furnace. He tried this experiment, and found his conjecture correct; the blast stimulated combustion, consequently the capability of the boiler to generate steam was greatly increased, and the power of the engine increased in the same proportion. No extra weight was added to the machine. The invention of this steam blast was almost the turning point in the history of the locomotive. Without it the engine would have been too clumsy and slow for practical use, but with it the greatest possibilities of use appeared.
Encouraged by the success of his steam blast Stephenson started to build a second locomotive. In this he planned an entire change in mechanical construction, his principal objects being the use of as few parts as possible, and the most direct possible application of power to the wheels. He took out a patent for this engine on February 28, 1815. This locomotive had two vertical cylinders that communicated directly with each pair of the four wheels that supported the engine, by means of a cross-head and a pair of connecting-rods. “Ball and socket” joints were used to make the union between the ends of the cross-heads where they united with the connecting-rods, and between the rods and the crank-pins attached to each driving-wheel. The mechanical skill of his workmen was not equal to the forging of all the necessary parts as Stephenson had devised them, and he was obliged to make use of substitutes which did not always work smoothly, but he finally succeeded in completing a locomotive which was a vast improvement on all earlier ones, and that was notable for the simple and direct communication between the cylinders and the wheels, and the added power gained by using the waste steam in the steam blast. This second locomotive of Stephenson’s was in the main the model for all those built for a considerable time.
During the time when Stephenson was working on his second locomotive explosions of fire-damp were unusually frequent in the coal mines of Northumberland and Durham, and for a space he turned his attention to the possibility of inventing some pattern of safety-lamp. The result was his perfection of a lamp that would furnish the miners with sufficient light and yet preclude risk of exploding fire-damp. This came to be known as the “Geordie Lamp,” to distinguish it from the “Davy Lamp” that Sir Humphrey Davy was inventing at about the same time. The lamp was used successfully by the miners at Killingworth, and was considered by many as superior to Davy’s lamp. Disputes arose as to which was invented first, and long controversies between scientific societies, most of which sided with the friends of Davy. Stephenson himself stated his claims firmly, but without rancor, and when he saw that it prevented the accidents in mines was satisfied that he had gained his object, and returned to the more absorbing subject of locomotives.
He realized that the road and the rails were almost as important as the engine itself. At that time the railways were laid in the most careless fashion, little attention was paid to the rails’ proper joining, and less to the grades of the roads. Stephenson laid down new rails at Killingworth with “half-lap joints,” or extending over each other for a certain distance at the ends, instead of the “butt joints” that were formerly used. Over these both the coal-cars drawn by horses and his locomotive ran much more smoothly. To increase this smoothness of travel he added a system of spring carriage to his engine, and saved it from the jolting that had handicapped his first model.
The second locomotive was proving so efficient at the Killingworth Colliery that friends of the inventor urged him to look into the possible use of steam in traveling on the common roads. To study this he made an instrument called the dynamometer, which enabled him to calculate the resistance of friction to which carriages would be exposed on railways. His experiments made him doubtful of the possibility of running such railroads, unless a great amount of very expensive tunneling and grading were first done.
All this time George Stephenson continued to study with his son Robert. The boy was employed at the colliery, and was rapidly learning the business under the skilful charge of his father. Stephenson had decided however that Robert should have a better education than had been his, and in 1820 took him from his post as viewer in the West Moor Pit, and sent him to the University of Edinburgh.
News spread slowly in England in that day, and the fact that a steam locomotive was being successfully used at Killingworth attracted very little attention in the rest of the country. Even in the neighborhood of the mines people soon grew used to seeing “Puffing Billy,” as the engine was called, traveling back and forth from the pit to the quay, and took it quite for granted. Here and there scattered scientific men, ever since Watt’s perfection of the steam-engine, had considered the possibility of travel by steam, but practical business men had failed to come forward to build a railway line. At length, however, Edward Pease, of Darlington, planned a road to run from Stockton to Darlington, and set about building it. He had a great deal of difficulty in forming a company to finance it, but he was a man of much perseverance, and at length he succeeded. While he was doing this Stephenson was patiently building new locomotives, and trying to induce the mine-owners along the Tyne to replace their horse-cars with his engines. In 1819 the owners of the Hetton Colliery decided to make this change, and asked Stephenson to take charge of the construction of their line. He obtained the consent of the Killingworth owners, and began work. On November 18, 1822, the Hetton Railway was opened. Its length was about eight miles, and five of Stephenson’s locomotives were working on it, under the direction of his brother Robert. In building this line George Stephenson was thoroughly practical. Although he knew that his name was becoming more and more identified with the locomotive engine, he did not hesitate to use stationary engines wherever he considered that they would be more economical. In the Hetton Railway, which ran for a part of its distance through rough country, he used stationary engines wherever he could not secure grades that would make locomotives practicable. His own steam-engines traveled over this line at the rate of about four miles an hour, and each was able to draw a train of seventeen coal wagons, weighing about sixty-four tons.
The coal mines of the Midlands and the north of England had been the original inducement to inventors to build engines that would draw cars, and the manufacturing needs of Manchester and Liverpool were now gradually inducing promoters to consider building railroads. The growth of Manchester and the towns close to it was tremendous, the cotton traffic between Manchester and Liverpool had jumped to enormous figures, and men felt that some new method of communication must be found. Robert Fulton’s friend, the Duke of Bridgewater, had been of some help with his canal system, but the trade quickly outstripped this service. Then William James, a man of wealth and influence, a large landowner and coal-operator, took up the subject of a Liverpool and Manchester Railway with some business friends, and had a survey of such a line begun. His men met with every possible resistance from the country people, who had no wish to have “Puffing Billys” racing through their fields; bogs had to be crossed and hills leveled; and it soon appeared that the cost of a road would be very expensive. The local authorities gave James and his associates some encouragement, but those members of Parliament he approached were more or less opposed to his plans. The time was not yet quite ripe for the road, but the needs of trade were growing more and more pressing.
Meantime Mr. Pease was again growing eager to build his Darlington and Stockton line. Near the end of the year 1821 two men called at his house. One introduced himself as Nicholas Wood, viewer at Killingworth, and then presented his companion, George Stephenson, of the same place. Stephenson had letters to Mr. Pease, and after a talk with him, persuaded him to go to the Killingworth Colliery and see his locomotives. Pease was much impressed with the engines he saw there, and even more with Stephenson’s ability as a practical engineer. The upshot of the matter was that Pease reported the results of his visit to the directors of his company, and they authorized him to secure Stephenson’s services in surveying the line they wished to build. He took up the work, made careful surveys and reports, and was finally directed to build a railway according to his own plans. This he did, working with the best corps of assistants and the most efficient materials he could find. When the line was nearly completed he made a tour of inspection over it with his son and a young man named John Dixon. Dixon later recalled that Stephenson said to the two as they came to the end of their trip, “Now, lads, I will tell you that I think you will live to see the day, though I may not live so long, when railways will come to supersede almost all other methods of conveyance in this country—when mail coaches will go by railway, and railroads will become the Great Highway for the king and all his subjects. The time is coming when it will be cheaper for a working man to travel on a railway than to walk on foot. I know there are great and almost insurmountable difficulties that will have to be encountered; but what I have said will come to pass as sure as we live.”
In spite of the powerful opposition that the company encountered, and the threats of the road trustees and others, the Stockton and Darlington line was opened for travel on September 27, 1825. A great concourse of people had gathered to see the opening of this first public railway. Everything went well. Stephenson himself drove the engine, and the train consisted of six wagons, loaded with coal and flour, then a special passenger coach, filled with the directors and their friends, then twenty-one wagons temporarily fitted with seats for passengers, and then six wagons of coal, making thirty-four carriages in all. A contemporary writer says, “The signal being given the engine started off with this immense train of carriages; and such was its velocity, that in some parts the speed was frequently twelve miles an hour; and at that time the number of passengers was counted to be four hundred and fifty, which, together with the coals, merchandise, and carriages, would amount to near ninety tons. The engine, with its load, arrived at Darlington, a distance of eight and three-quarter miles, in sixty-five minutes. The six wagons loaded with coals, intended for Darlington, were then left behind; and, obtaining a fresh supply of water and arranging the procession to accommodate a band of music, and numerous passengers from Darlington, the engine set off again, and arrived at Stockton in three hours and seven minutes, including stoppages, the distance being nearly twelve miles.” By the time the train reached Stockton there were about six hundred people riding in the cars or hanging on to them, and the train traveled on a steady average of four to six miles an hour from Darlington.
This road was primarily built to transport freight, and passengers were in reality an afterthought. But the directors decided to try a passenger coach, and accordingly Stephenson built one. It was an uncouth carriage, looking something like a caravan used at a country fair. The doors were at the ends, a row of seats ran along each side of the interior, and a long deal table extended down the centre. Stephenson called this coach the “Experiment,” and in a short time it had become the most popular means of travel between Stockton and Darlington.
With the Stockton and Darlington Railway an assured and successful fact, the men who had been interested in building a line between Liverpool and Manchester earlier took up the subject again. Some improvement in the means of communication between the two cities was more needed than ever. The three canals and the turnpike road were often so crowded that traffic was held up for days and even weeks. In addition the canal charges were excessive. On the other hand the railway builders had to meet the opposition of the powerful canal companies and landowners along the line they wished to open, and it took time and ingenuity to accomplish working adjustments.
The Liverpool and Manchester Railway bill came up for consideration in the House of Commons early in 1825. A determined stand was made against it, and the promoters and their engineers, chief among whom was Stephenson, had to be very modest in their claims. Stephenson had said to friends that he was confident that locomotives could be built that would carry a train of cars at the rate of twenty miles an hour, but such a claim would have been received by the public as ridiculous, and the engineer laughed to scorn. His opponents tried to badger him in every way they could, and ridicule even his modest statements. “Suppose now,” said one of the members of Parliament in questioning him, “one of these engines to be going along a railroad at the rate of nine or ten miles an hour, and that a cow were to stray upon the line and get in the way of the engine; would not that be a very awkward circumstance?” “Yes,” answered Stephenson, with a twinkling eye, “very awkward—for the coo!”
In fact very few of the members understood Stephenson’s invention at all. A distinguished barrister represented about the general level of ignorance when he said in a speech, “Any gale of wind which would affect the traffic on the Mersey would render it impossible to set off a locomotive engine, either by poking the fire, or keeping up the pressure of the steam till the boiler was ready to burst.” Against such opposition it was not surprising that the bill failed of passage that year.
But the necessities of commerce could not be denied, and the following year the bill came up again, and was passed. Stephenson, as principal engineer of the railway, at once began its building. This in itself was a unique and very remarkable feat. An immense bog, called Chat Moss, had to be crossed, and Stephenson was the only one of the engineers concerned who did not doubt whether such a crossing were really possible. Ditches that were dug to drain the bog immediately filled up; as soon as one part was dug out the bog flowed in again; it swelled rapidly in rainy weather, and piles driven into it would sink down into the mire. But Stephenson finally built his road across it. A matting of heath and the branches of trees was laid on the bog’s surface, and in some places hurdles interwoven with heather; this floating bed was covered over with a few inches of gravel, and on this the road proper was constructed. In addition to the crossing of Chat Moss a tunnel of a mile and a half had to be cut under part of Liverpool, and in several places hills had to be leveled or cut through. The old post-roads had never had to solve such problems, and George Stephenson deserves to rank as high as a pioneer of railroad construction as he does as builder of the working locomotive.
The directors of the railway were anxious to secure the best engine possible, and opened a general competition, naming certain conditions the engine must fulfil. Stephenson and Henry Booth built the “Rocket,” and, as this was the only engine that fulfilled all the conditions, took the prize. The “Rocket” was by far the most perfect locomotive yet built, having many new improvements that Stephenson had recently worked out.
The “Rocket” would make thirty miles an hour, a wonderful achievement, and was put to work drawing the gravel that was used in building the permanent road across Chat Moss. With the aid of such a powerful engine the work went on more rapidly, and in June, 1830, a trial trip was made from Liverpool to Manchester and back. There was a huge gathering at the stations at each end of the line. The train was made up of two carriages, filled with about forty passengers, and seven wagons loaded with stores. The “Rocket” drew this train from Liverpool to Manchester in two hours and one minute, and made the return trip in an hour and a half. It crossed Chat Moss at the rate of about twenty-seven miles an hour.
The public opening of the new road occurred on September 15, 1830. By that time Stephenson had built eight locomotives, and they were all ready for service. Much of the opposition of the general public had been overcome, and the opening was considered a great national event. The Duke of Wellington, then Prime Minister, Sir Robert Peel, and many other prominent men were present. George Stephenson drove the first engine, the “Northumbrian,” and was followed by seven other locomotives and trains, carrying about 600 passengers. Stephenson’s son drove the second engine, and his brother the third. They started from Liverpool, and the people massed along the line cheered and cheered again as they saw the eight trains speed along at the rate of twenty-four miles an hour.Unfortunately an accident occurred about seventeen miles out of Liverpool. The first engine, with the carriage containing the Duke of Wellington, had been stopped on a siding so that the Duke might review the other trains. Mr. Huskisson, one of the members of Parliament for Liverpool, and a warm friend and supporter of Stephenson and the railroad, had stepped from his coach, and was standing on the railway. The Duke called to him, and he crossed over to shake hands. As they grasped hands the bystanders began to cry, “Get in, get in!” Confused, Mr. Huskisson tried to go around the open door of the carriage, which projected over the opposite rail. As he did so he was hit by the “Rocket,” an engine coming up on the other track, was knocked down, and had one leg crushed. That same night he died in the near-by parsonage of Eccles. This first serious railway accident, occurring at the very opening of the line, cast a gloom over the event. It revealed something of the danger coincident with the new invention. The Duke of Wellington and Sir Robert Peel both expressed a wish that the trains should return to Liverpool, but when it was pointed out that a great many people had gathered from all the neighboring country at Manchester, and that to abandon the opening would jeopardize the whole future success of the road, they agreed to go on. The journey was completed without any further mishap, and the people of Manchester gave the eight trains a warm welcome.
With the opening of this line the success of the railroad as a practical means of conveyance became assured. Singularly enough the builders of the railroad had based their estimates almost entirely on merchandise traffic, and had stated to the committee of the House of Commons that they did not expect their passenger coaches to be more than half filled. The carriages they planned to use would have carried 400 to 500 persons if full, but the road was hardly open before the company had to provide accommodations to carry 1,200 passengers daily, and the receipts from passenger travel immediately far exceeded the receipts from carrying freight.
Similarly the directors had expected that the average speed of the locomotives would be about nine or ten miles an hour, but very soon the trains were carrying passengers the entire thirty miles between Liverpool and Manchester in a little more than an hour. Travel by stage-coach had taken at least four hours, so that the railroad reduced the time nearly one-fourth. Engineers who came from a distance to examine the railroad were amazed at the smoothness of travel over it. Two experts from Edinburgh declared that traveling on it was smoother and easier than any they had known over the best turnpikes of Mr. Macadam. They said that even when the train was going at the very high speed of twenty-five miles an hour they “could observe the passengers, among whom were a good many ladies, talking to gentlemen with the utmost sang froid.”
Business men were delighted at being able to leave Liverpool in the morning, travel to Manchester, do business there, and return home the same afternoon. The price of coal, and the cost of carrying all classes of goods, was tremendously reduced. Another result, which was the opposite of what had been expected, was that the price of land along the line and near the stations at once rose. Instead of the noise and smoke of the trains frightening people away it seemed to charm them. The very landlords who had driven the surveyors off their property and done everything they could to hinder the builders now complained if the railroad did not pass directly through their domains, and begged for stations close at hand. Even the land about Chat Moss was bought up and improved, and all along the line what had been waste stretches began to blossom into towns and villages.
Stephenson continued to make improvements to his locomotives. He had already added the multitubular boiler, the idea of which was to increase the evaporative power of the boiler by adding to its heating surface by means of many small tubes filled with water. This increase of evaporative power increased the speed the engine could attain. In his new engine, the “Samson,” he adopted the plan of coupling the fore and rear wheels of the engine. This more effectually secured the adhesion of the wheels to the rails, and allowed the carrying of heavier loads. He improved the springs of the carriages, and built buffers to prevent the bumping of the carriage ends, which had been very unpleasant for the earliest passengers. He also found a new method of lubricating his carriage axles, his spring frames, the buffers, and the brakes he had built for the trains.
The Liverpool and Manchester Railway was to be followed rapidly by other lines. George Stephenson was a good man of business as well as a good engineer. He suggested a number of lucrative opportunities to his Liverpool friends, and he took a financial share in some of them himself. He thought there should be a line between Swannington and Leicester, in order to increase the coal supply of the latter town, which was quite a manufacturing centre. A company was formed, and his son Robert was appointed engineer. In the course of the work Robert learned that an estate near the road was to be sold, and decided that there was considerable coal there. George Stephenson and two other friends bought the place, and he took up his residence there, at Alton Grange, in order to supervise the mining operations. The mine was very successful, and the railroad proved of the greatest value to the people of Leicester. Stephenson now changed his position from that of an employee of coal-owners to that of employer of many miners himself.
The first railroads to be built were principally branches of the Liverpool and Manchester one, and chiefly located in the mining and manufacturing county of Lancaster. But before long the great metropolis of London required railroad communication with the Midlands, and the London and Birmingham road was projected. Here again the promoters had to overcome gigantic obstacles, the opposition of the great landed proprietors who owned vast estates in the neighborhood of London, the opposition of the old posting companies, and of the conservative element who were afraid of the great changes such a method of transportation would bring about. The natural difficulties of the first lines were increased a hundredfold, greater marshes had to be crossed, greater streams to be bridged, greater hills to be tunneled. But the greater the obstacles the greater Stephenson’s resources proved. When some of his tunnels were flooded, because the workmen had cut into an unexpected bed of quicksand, he immediately designed and built a vast system of powerful pumps, and drew off enough water to fill the Thames from London Bridge to Woolwich, so that his workmen might continue the tunnels and line them with masonry sufficiently solid to withstand any future inrush of water.
The men who were back of this railroad would very probably never have projected it had they realized that the building of it would cost five million pounds. But when the road was opened for use the excess in traffic beyond the estimates was much greater than the excess in cost had been. The company was able to pay large dividends, and the builders found that they could have made no better investment. This London and Birmingham road, 112 miles long, was opened September 17, 1838. The receipts from passenger traffic alone for the first year were £608,564. Evidently travel by coach had not been as popular in reality as the conservatives had ardently maintained.
It is curious to note the many kinds of opposition these first railways encountered. Said Mr. Berkeley, a member of Parliament for Cheltenham, “Nothing is more distasteful to me than to hear the echo of our hills reverberating with the noise of hissing railroad engines running through the heart of our hunting country, and destroying that noble sport to which I have been accustomed from my childhood.” One Colonel Sibthorpe declared that he “would rather meet a highwayman, or see a burglar on his premises, than an engineer; he should be much more safe, and of the two classes he thought the former more respectable!” Sir Astley Cooper, the eminent surgeon, said to Robert Stephenson, when the latter called to see him about a new road, “Your scheme is preposterous in the extreme. It is of so extravagant a character as to be positively absurd. Then look at the recklessness of your proceedings! You are proposing to cut up our estates in all directions for the purpose of making an unnecessary road. Do you think for one moment of the destruction of property involved in it? Why, gentlemen, if this sort of thing is allowed to go on, you will in a very few years destroy the noblesse!” Physicians maintained that travel through tunnels would be most prejudicial to health. Dr. Lardner protested against passengers being compelled to put up with what he called “the destruction of the atmospheric air,” and Sir Anthony Carlisle insisted that “tunnels would expose healthy people to colds, catarrhs, and consumption.” Many critics expected the boilers of the locomotives to explode at any and all times. Others were sure that the railways would throw so many workmen out of employment that revolution must follow, and still others declared that England was being delivered utterly into the power of a small group of manufacturers and mine-owners. But in spite of all this the people took to riding on the railways and England prospered.
The aristocracy held out the longest. Noblemen did not relish the thought of traveling in the same carriages with workmen. The private coach had for long been a badge of station. For a time, therefore, the old families and country gentility sent their servants and their luggage by train, but themselves jogged along the old post-roads in the family chariots. But there were more accidents and more delays in travel by coach than by train, and so, one by one, they pocketed their pride and capitulated. The Duke of Wellington, who had seen the accident to Mr. Huskisson near Liverpool, held out against such travel for a long time. But when Queen Victoria, in 1842, used the railway to go from London to Windsor, the last resistance ended, and the Iron Duke, together with the rest of his order, followed the Queen’s example. Said the famous Dr. Arnold of Rugby, as he watched a train speeding through the country, “I rejoice to see it, and think that feudality is gone forever. It is so great a blessing to think that any one evil is really extinct.”
Stephenson himself was one of the busiest men in the kingdom. He was engineer of half a dozen lines that were building, and he traveled incessantly. Many nights the only sleep he had was while sitting in his chaise riding over country roads. At dawn he would be at work, surveying, planning, directing, until nightfall. In three years he surveyed and directed the construction of the North Midland line, running from Derby to Leeds, the York and North Midland, from Normanton to York, the Manchester and Leeds, the Birmingham and Derby, and the Sheffield and Rotherham. And in addition to this he traveled far and wide to give advice about distant lines, to the south of England, to Scotland, and to the north of Ireland to inspect the proposed Ulster Railway. He took an office in London, in order that he might take part in the railway discussions that were continually coming before Parliament. His knowledge of every detail relating to the subject was enormous. He knew both the engineering and the business sides most intimately. “In fact,” he said to a committee of the House of Commons in 1841, “there is hardly a railway in England that I have not had to do with.” Yet in spite of all this work he found time to look after his coal mines near Chesterfield, to establish lime-works at Ambergate, on the Midland Railway, and to superintend his flourishing locomotive factory at Newcastle.
King Leopold of Belgium invited him to Brussels, and there discussed with him his plans for a railway from Brussels to Ghent. The King made him a Knight of his Order of Leopold, and when the railway was finished George Stephenson was one of the chief guests of honor at the opening. Later he went to France, where he was consulted in regard to the new line that was building between Orleans and Tours. From there he went to Spain to look into the possible construction of a road between Madrid and the Bay of Biscay. He found the government of Spain indifferent to the railway, and there were many doubts as to whether there would be sufficient traffic to pay the cost of construction. His report to the shareholders in this proposed “Royal North of Spain Railway” was therefore unfavorable, and the idea was shortly after abandoned.
Stephenson had moved his home from Alton Grange to Tapton House in 1838. The latter place was a large, comfortable dwelling, beautifully situated among woods about a mile to the northeast of Chesterfield. Here he lived the life of a country gentleman, free to indulge the strong love of nature that had always been one of his leading characteristics. He began to grow fine fruits and vegetables and flowers, and his farm and gardens and hothouses became celebrated all over England. He was continually sought out by inventors and scientific men, who wanted his views on their particular work. He also spent some time at Tapton in devising improvements for the locomotive. One of these was a three-cylinder locomotive, and such an engine was later used successfully on the North Eastern Railway. It was, however, found to be too expensive an engine for general railroad use. He also invented a new self-acting brake. He sent a model of this to the Institute of Mechanical Engineers at Birmingham, of which he was president, together with a report describing it in full. “Any effectual plan,” he wrote, “for increasing the safety of railway traveling is, in my mind, of such vital importance, that I prefer laying my scheme open to the world to taking out a patent for it; and it will be a source of great pleasure to me to know that it has been the means of saving even one human life from destruction, or that it has prevented one serious concussion.”
He also gave great assistance to his son Robert, who was rapidly becoming a railway engineer second only to his father in fame. George Stephenson began the line from Chester to Holyhead, which was completed by Robert. Robert designed the tubular bridge across the Menai Straits on this line, which was considered a most remarkable feat. Permission could not be obtained to interfere with the navigation of the Straits in the slightest degree during the building, and so piers and arches could not be used. It occurred to Robert Stephenson that the train might be run through a hollow iron beam. Two tubes, which were to form the bridge, were made of wrought iron, floated out into the stream, and raised into position. This new and original railway bridge proved a success, and convinced England that Robert had inherited his father’s genius for surmounting what seemed impossible natural difficulties. George Stephenson did not live to see this line completed. He died August 12, 1848.
In many respects Stephenson was like Watt. He came from the working classes, inheriting no special gift for science, and little leisure to follow his own bent. What he learned he got at first hand, in the coal mines and the engine shops. What he accomplished was due largely to indomitable perseverance. Others had built steam-engines that were almost successful as locomotives, but for one reason or another had never pushed their invention to that point where the world could actually use it. When Stephenson had built his locomotive he fought for it, he made men take an interest in it, and the world accept it. He always spoke of his career as a battle. “I have fought,” said he, “for the locomotive single-handed for nearly twenty years, having no engineer to help me until I had reared engineers under my own care.” And again he said, “I put up with every rebuff, determined not to be put down.”
Stephenson did for the locomotive what Watt did for the condensing engine. He took the primitive devices of other men, and by the rare powers of selection, combination, and invention produced a finished product of wonderful power and efficiency. True it is that neither Watt nor Stephenson were the first men to conceive of a steam-engine or a locomotive, nor even the first to build working models, but they were the first to finish what they began, and add the steam-engine and the locomotive to the other servants of men.
Dr. Arnold was doubtless right when he looked upon the railway as presaging the end of the feudal system. Its value is beyond any estimate. It has widened man’s horizon, and given him all the lands instead of only the limits of his homestead.
There is a peculiar charm attaching to the figure of Robert Fulton, the attraction that plays about the man who is many-sided, and picturesque on whatever side one looks at him. He was a man at home on both shores of the Atlantic, at a time when such men were rare. He had been taught drawing by Major André, when the latter was a prisoner of war in the little Pennsylvania town of Lancaster. He had hung out his sign as Painter of Miniatures at the corner of Second and Walnut Streets in Philadelphia, under the friendly patronage of Benjamin Franklin. He had lodged in London at the house of Benjamin West, and shown his pictures at the Royal Academy. Two great English noblemen became his allies in scientific studies. Napoleon, as First Consul, bargained with him over his invention of torpedoes. Finally he sent the little Clermont up the Hudson under steam. There was a man of rare ability, one who had many hostages to give to fortune. He was the artist turned inventor, as many another has done, and if he was not as great an artist as Leonardo da Vinci neither was Leonardo as great an inventor as Robert Fulton.
Fulton invented a machine for cutting marble, one for spinning flax, a double inclined plane for canal navigation, a machine for twisting rope, an earth-scoop for canal and irrigation purposes, a cable-cutter, the earliest French panorama, a submarine torpedo boat, and the steamboat. Other men had worked over steamboats, but he reached the goal. He made the steamboat practicable, as Watt had the steam-engine. Above all, he was very fortunate; he found his countrymen ready to welcome the Clermont, and to fall in with his plans, an attitude which had not faced certain men in England and in France who had built similar boats earlier than Fulton. Some engineers have been tempted to call him a lucky amateur, a talented artist who happened to become interested in new methods of navigation. If one grants all this there is still the fact that it was the Clermont’s success that opened the watercourses of the world to steam.
“Quicksilver Bob” he was called as a boy in Lancaster, because he used to buy all that metal he could for experiments. Even then he was many-sided. He made designs for firearms and experimented with guns to learn the carrying distance of various bores and balls. There was a factory in Lancaster where arms were being made for the Continental troops, and “Quicksilver Bob” was given the run of the place. In addition he painted signs to hang before the village shops and taverns.
To simplify his fishing expeditions he made a model of a boat propelled by paddles, and later he built such a boat and used it on the Conestoga River. No one could tell what he would turn to next. When Hessian prisoners were kept in the neighborhood the town boys would go out to look at them, and Robert would make sketches of them. These sketches gave him a local reputation, and his friends were not surprised when at seventeen he left Lancaster to seek his fortune as a painter of portraits and miniatures in Philadelphia.
He was well liked in the city. He had a talent for friendship, which, combined with good looks, more than ordinary intelligence, and most uncommon industry, carried him far. He drew plans for machinery, he designed houses and carriages, he worked as professional painter. Franklin became his patron and adviser. Then illness sent him to the fashionable hot springs of Virginia, and there he heard so much talk of England and of France that he decided to see those countries for himself. Before he left America he bought a farm in Washington County, Pennsylvania, in order to insure a home for his mother and sisters. That done, he sailed for England, with a packet of letters of introduction, in 1786.
In London Fulton professed himself to be an artist, although his thoughts were constantly tending toward inventions. He lived at the house of Benjamin West, and painted, and his portraits were shown at the Royal Academy and at the Society of Artists. Betimes he enjoyed himself in society and in trips to the counties. He journeyed into Devonshire and stayed at Powderham Castle, copying famous pictures there. Wherever he went he made friends, and their influence was constantly helping him forward on what must have been a somewhat precarious career.
Two of these friends, the Duke of Bridgewater and the Earl of Stanhope, were scientists of repute. The Duke owned a great estate, of untold mineral wealth, which had never been properly worked because of lack of transportation facilities. He had recently built several canals on this property, and was at the head of a number of companies which were planning to intersect England with waterways. He interested Fulton in his schemes and gradually weaned his thoughts away from art to civil engineering. The Earl of Stanhope corresponded with him over the possibility of propelling boats by steam, and in these letters Fulton first gave the outlines of the plans he was later to perfect in the Clermont. The Earl was deeply interested, and encouraged the young American to persevere, but for the time Fulton left the steamboat to work out other problems.
The possibility of a great English canal system appealed to him strongly, and in 1794 he obtained an English patent for a double inclined plane for raising and lowering canal boats. Later he took English patents on a machine for spinning flax, and on a new device for twisting hemp rope. There followed others for a machine that should scoop out earth to make canals or aqueducts, for a “Market or Passage Boat” to use on canals, and for a “Dispatch Boat” that should travel quickly. He sent drawings of all these inventions to his influential friends, hoping that they would push them, and he also wrote and published “A Treatise on Canal Navigation.” By this time he would seem to have given up all thought of the artist’s career, and to have turned his talent with the pen to the aid of his mechanical drawings.
The French Revolution was imminent, and Fulton was busy studying the conditions that were leading to it. He believed that Free Trade would tend to abolish many of the difficulties that divided nations, and he wrote a paper on that subject, addressed to the French Directory. He believed in democracy, but he was strongly of the opinion that the young American republic should take no part in the struggle for liberty in Europe. In a letter written in 1794 he says, “It has been much Agitated here whether the Americans would join the French. But I Believe every Cool friend to America could wish them to Remain nuter. The americans have no troublesome Neighbors, they are without foreign Possessions, and do not want the alliance of any Nation, for this Reason they have nothing to do with foreign Politics. And the Art of Peace Should be the Study of every young American which I most Sincerely hope they will maintain.”
But Fulton himself was in a manner to be drawn into the turmoil. When France had quieted somewhat England began that policy of aggression on the sea toward American ships and crews that was to lead to the War of 1812. Fulton’s attention was drawn from canal-building to the possibility of some invention that might tend to subserve peace, and this in time led him to design and build the first torpedo.
Again Fulton’s talent for friendship stood him in good stead. When he had left London for Paris he called upon Joel Barlow, poet and American diplomat, and was urged to take up his residence first at the hotel where the Barlows were staying, and later at their house. For seven years Fulton lived with them, busy about the most diverse matters, and always keenly interested in the struggles of the new and hot-tempered republic. A rich American had bought a tract of central real estate in Paris and had built a row of shops arranged on the two sides of a cloister. Fulton suggested that he add a panorama to the other buildings, and the idea was adopted. Fulton was given charge, and by 1800 he had built and opened the first panorama that Paris had ever seen. The show made money, and the inventor, a perfect Jack-of-all-trades, added another feather to his varicolored cap.
In December, 1797, Fulton had interested his friend Barlow in a machine intended to drive “carcasses” of gunpowder under water. But his first experiments at exploding the gunpowder at a definite moment failed. Then he moved to Havre, where he would have greater opportunity to try out his torpedo-boats, as he christened them. His idea was that if his invention succeeded war would be made so dangerous that nations would be obliged to keep peace. Barlow was able to assist him with money until he had built and actually navigated some of his torpedoes along the coast. When he had satisfied himself, he wrote to the French government, the Directory, offering them his invention for use against their enemies.
The Directory was pleased with the offer, but the government was in so much of a turmoil that it was months before any positive action was taken. At length, on February 28, 1801, Fulton received word from Napoleon, the First Consul, to send his torpedo-boat against the English fleet. He set out; but the English fleet did not come his way, and he spent the summer vainly reconnoitering along the coast. To show the value of his invention he arranged to attack a sloop. This he described in his letter to the French Commission on Submarine Navigation. “To prove this experiment,” he wrote, “the Prefect Maritime and Admiral Villaret ordered a small Sloop of about 40 feet long to be anchored in the Road, on the 23rd of Thermidor. With a bomb containing about 20 pounds of powder I advanced to within 200 Metres, then taking my direction so as to pass near the Sloop, I struck her with the bomb in my passage. The explosion took place and the sloop was torn into atoms, in fact, nothing was left but the buye [buoy] and cable. And the concussion was so great that a column of Water, Smoke and fibres of the Sloop were cast from 80 to 100 feet in Air. This simple Experiment at once proved the effect of the Bomb Submarine to the satisfaction of all the Spectators.”
This exhibition took place in August, 1801, before a crowd of onlookers, and at once established the value of the torpedo. But, as he was unable to attack any English ships, the French government lost interest in his invention, and Napoleon’s scientific advisers reported to him that they regarded the young American as “a visionary.”
At the same time the British government awakened to the great possibilities of Fulton’s device. His old friend, Lord Stanhope, urged that suitable offers be made him. This was ultimately done, and in April, 1804, Fulton left France and returned to London. A contract was drawn up by which he was to put his torpedo at the service of the English government and receive in return two hundred pounds a month and one-half the value of all ships that might be destroyed by his invention.
This arrangement, however, was of short duration. A change of ministry dampened his hopes, and in 1806 the government declined to adopt his invention on his terms. At the same time they tried to suppress this new method of warfare, and to that end made him another offer. Fulton, always an ardent patriot, answered, “At all events, whatever may be your reward, I will never consent to let these inventions lie dormant should my Country at any time have need of them. Were you to grant me an annuity of £20,000 a year, I would sacrifice all to the safety & independence of my Country. But I hope that England and America will understand their mutual Interest too well to War with each other And I have no desire to Introduce my Engines into practice for the benefit of any other Nation.”
He was already eager to return home to work upon his long cherished plans for a steamboat. He continues, “As I am bound in honor to Mr. Livingston to put my steamboat in practice and such engine is of more immediate use to my Country than Submarine Navigation, I wish to devote some years to it and should the British Government allow me an annuity I should not only do justice to my friends but it would enable me to carry my steamboat and other plans into effect for the good of my Country.—It has never been my intention to hide these Inventions from the World on any consideration, on the contrary it has been my intention to make them public as soon as consistent with strict justice to all with whom I am concerned. For myself I have ever considered the interest of America [n] free commerce, the interest of mankind, the magnitude of the object in view and the rational reputation connected with it superior to all calculations of a pecuniary kind.”
Satisfactory terms of agreement were reached, and in 1806 Fulton was free and ready to return to that native land from which he had been away twenty years.
The building of a practicable steamboat had long been in his mind. He had corresponded on the subject with Chancellor Livingston, who had devoted much time and money to new inventions. Fulton, when in Paris, had experimented with models of steamboats, and had studied the records of what had already been done in that line. In 1802 he had started a course of calculations on the resistance of water, and the comparative advantages of the known means of propelling vessels. He had rejected the plan of using paddles or oars, and also of forcing water out of the stern of the vessel, and had retained the idea of the paddle-wheel. This he tried successfully on a small model that he built and used on a river that ran through the village of Plombières. He then built an experimental boat, sixty-six feet long and eight feet wide, and this he exhibited to a large audience of Parisians in August, 1803. His success led him to order certain parts of a steam-engine from the firm of Boulton and Watt in Birmingham, these to be shipped to America. Meantime Chancellor Livingston had obtained for himself and Fulton the exclusive right to navigate the waters of New York state by vessels propelled by fire or steam.
As soon as he reached America in December, 1806, Fulton started work on his boat. He engaged Charles Brownne, a ship-builder on the East River, to lay down the hull. He decided to name the vessel the Clermont, the name of Chancellor Livingston’s country-place on the Hudson, where Fulton had been a guest. The engine duly arrived from Birmingham and was carried to the shipyard. As a number of loafers and hangers-on about the docks threatened injury to “Fulton’s Folly,” as the building boat was called, he had to engage watchmen to guard his property. By August the boat was finished, and was moved by her own engine from the yards to the Jersey shore. She was one hundred and fifty feet long, thirteen feet wide, and drew two feet of water. Before she had gone a quarter of a mile both passengers and observers on the shore were satisfied that the steamboat was a thoroughly practicable vessel.
On Sunday, August 9, 1807, Fulton made a short trial trip of the Clermont, and wrote an account of it to Livingston. “Yesterday about 12 o’clock I put the steamboat in motion first with a paddle 8 inches broad, 3 feet long, with which I ran about one mile up the East River against a tide of about one mile an hour, it being nearly high water. I then anchored and put on another paddle 8 inches wide, 3 feet long, started again and then, according to my best observations, I went 3 miles an hour, that is two against a tide of one: another board of 8 inches was wanting, which had not been prepared, I therefore turned the boat and ran down with the tide—and turned her round neatly into the berth from which I parted. She answers the helm equal to anything that ever was built, and I turned her twice in three times her own length. Much has been proved by this experiment. First that she will, when in complete order, run up to my full calculations. Second, that my axles, I believe, will be sufficiently strong to run the engine to her full power. Third, that she steers well, and can be turned with ease.”It was on August 17, 1807, that the Clermont made her first historic trip up the Hudson. At one o’clock she cast off from her dock near the State’s Prison, in what was called Greenwich Village, on the North River. The inventor described the voyage characteristically to a friend. He wrote, “The moment arrived in which the word was to be given for the boat to move. My friends were in groups on the deck. There was anxiety mixed with fear among them. They were silent, sad and weary. I read in their looks nothing but disaster, and almost repented of my efforts. The signal was given and the boat moved on a short distance and then stopped and became immovable. To the silence of the preceding moment, now succeeded murmurs of discontent, and agitations, and whispers and shrugs. I could hear distinctly repeated—‘I told you it was so; it is a foolish scheme: I wish we were well out of it.’
“I elevated myself upon a platform and addressed the assembly. I stated that I knew not what was the matter, but if they would be quiet and indulge me for half an hour, I would either go on or abandon the voyage for that time. This short respite was conceded without objection. I went below and examined the machinery, and discovered that the cause was a slight maladjustment of some of the work. In a short time it was obviated. The boat was again put in motion. She continued to move on. All were still incredulous. None seemed willing to trust the evidence of their own senses. We left the fair city of New York; we passed through the romantic and ever-varying scenery of the Highlands; we descried the clustering houses of Albany; we reached its shores,—and then, even then, when all seemed achieved, I was the victim of disappointment.
“Imagination superseded the influence of fact. It was then doubted if it could be done again, or if done, it was doubted if it could be made of any great value.”
But the Clermont, in spite of all prophecies to the contrary, had traveled under her own steam from New York to Albany, and the trip was the crowning event in Fulton’s career as inventor. At the time she made that first voyage the Clermont was a very simple craft, decked for a short distance at bow and stern, the engine open to view, and back of the engine a house like that on a canal-boat to shelter the boiler and provide an apartment for the officers. The rudder was of the pattern used on sailing-vessels, and was moved by a tiller. The boiler was of the same pattern used in Watt’s steam-engines, and was set in masonry. The condenser stood in a large cold-water cistern, and the weight of the masonry and the cistern greatly detracted from the boat’s buoyancy. She was so very unwieldy that the captains of other river boats, realizing the danger of the steamboat’s competition, were able to run into her, and make it appear that the fault was hers; and as a result she several times reached port with only a single wheel.
There were almost as many quaint descriptions of the boat as there were people who saw it. One described it as an “ungainly craft looking precisely like a backwoods sawmill mounted on a scow and set on fire.” Others said the Clermont appeared at night like a “monster moving on the waters defying the winds and tide, and breathing flames and smoke.” Some of the ignorant along the Hudson fell on their knees and prayed to be delivered from the monster. The boat must have been a very strange sight; pine wood was used for fuel, and when the engineer stirred the fire a torrent of sparks went shooting into the sky.
The boat was clumsy beyond question. The exposed machinery creaked and groaned, the unguarded paddle-wheels revolved ponderously and splashed a great deal of water, the tiller was badly placed for steering. Fulton quickly remedied some of the defects, and the Clermont that began to make regular runs from New York to Albany a little later was quite a different boat from that which made her maiden voyage on August 17th.
In spite of Fulton’s gloomy tone in his letter there were many among the men and women who made the first trip with him who were not dubious concerning the invention. As soon as the first difficulties were overcome and the boat was moving on a steady keel, the passengers, most of whom were close friends of Fulton and of Chancellor Livingston, broke into song. As they passed by the Palisades it is said they sang “Ye Banks and Braes o’ Bonny Doon.” Fulton himself could not be overlooked. A contemporary described him: “Among a thousand individuals you might readily point out Robert Fulton. He was conspicuous for his gentle, manly bearing and freedom from embarrassment, for his extreme activity, his height, somewhat over six feet,—his slender yet energetic form and well accommodated dress, for his full and curly dark brown hair, carelessly scattered over his forehead and falling around his neck. His complexion was fair, his forehead high, his eyes dark and penetrating and revolving in a capacious orbit of cavernous depths; his brow was thick and evinced strength and determination; his nose was long and prominent, his mouth and lips were beautifully proportioned, giving the impress of eloquent utterance. Trifles were not calculated to impede him or damp his perseverance.”
Fulton was now forty-two years old, and famous on both sides of the Atlantic. He asked Harriet Livingston, a near relation of his friend the Chancellor, to become his wife. She accepted him, and he was warmly welcomed into that rich and influential family.
On September 2, 1807, Fulton advertised regular sailings of the Clermont between New York and Albany. These proved popular, and other routes were soon planned. That winter he made many changes in the vessel and worked out certain devices that he wished to patent. The name of Clermont was changed to the North River the following spring, and the reconstructed steamboat continued in regular service on the Hudson for a number of years. In the succeeding year he built other boats, the Rariton, to run from New York to New Brunswick, and The Car of Neptune as a second Hudson River boat. He was very much occupied perfecting new commercial schemes, protecting his patents from a horde of pirates, and planning to introduce his invention into Europe. Before his death in 1815, eight years after the Clermont’s first trip, he had built seventeen boats, among them the first steam war frigate, a torpedo boat, and the first steam ferry-boats with rounded ends to be used for approaching opposite shores.
A century has not dimmed Fulton’s fame, nor set aside his claim to be the practical inventor of the steamboat. He built the first one to be used in American waters, and his model was copied in all other countries. He carried his ideas to completion, and that, with his talent to observe and improve upon other men’s work, gave him his leading place among the world’s pioneers.
At first sight the wireless telegraph seems the most wonderful of all inventions and discoveries, the one that is least easy to understand, and that most nearly approaches that magic which is above all nature’s laws. Even if we do come to understand it it loses nothing of its wonder, and the last impression is very like the first. We can understand how an electric current travels through a wire, even if we cannot understand electricity, but how that current can travel through limitless space and yet reach its destination strains the imagination. Yet wireless telegraphy is not a matter of the imagination, but of exact, demonstrable science.
On December 12, 1901, a quiet, dark-skinned young man sat, about noontime, in a room of the old barracks building on Signal Hill, near St. John’s, Newfoundland. On the table in front of him was a mechanical apparatus, with an ordinary telephone receiver at its side. The window was partly open, and a wire led from the machine on the table through the window to a gigantic kite that a high wind kept flying fully 400 feet above the room. The young man picked up the receiver, and held it to his ear for a long time. His face showed no sign of excitement, though an assistant, standing near him, could barely keep still. Then, suddenly, came the sharp click of the “tapper” as it struck the “coherer.” That meant that something was coming. The young man listened a few minutes, and then handed the receiver to his assistant. “See if you can hear anything, Mr. Kemp,” said he. The other man took the receiver, and a moment later his ear caught the sound of three little clicks, faint, but distinct and unmistakable, the three dots of the letter S in the Morse Code. Those clicks had been sent from Poldhu, on the Cornish coast of England, and they had traveled through air across the Atlantic Ocean without any wire to guide them. That was one of the great moments of history. The young man at the table was Guglielmo Marconi, an Italian.
We know that it is no injustice to a great inventor to say that other men had imagined what he achieved, and had earlier tried to prove their theories. It takes nothing from the glory of that other great Italian, Columbus, to recall that other sailors had planned to cross the sea to the west of Europe and that some had tried it. So James Clerk-Maxwell had proved by mathematics the electro-magnetic theory of light in 1864, and Heinrich Hertz had demonstrated in 1888 by actual experiment that electric waves exist in the free ether, and Edison had for a time worked on the problem of a wireless telegraph. Marconi devised the last link that made the wonder possible, and caught the first click that came across the sea, and to him belong the palms. Judge Townsend, in deciding a suit in a United States court in 1905, declared, “It would seem, therefore, to be a sufficient answer to the attempts to belittle Marconi’s great invention that, with the whole scientific world awakened by the disclosures of Hertz in 1887 to the new and undeveloped possibilities of electric waves, nine years elapsed without a single practical or commercially successful result, and Marconi was the first to describe and the first to achieve the transmission of definite intelligible signals by means of these Hertzian waves.”
Marconi was born at Villa Griffone, near Bologna, in 1874, so that he was under thirty when he caught that first transatlantic message. He studied at Leghorn under Professor Rosa, and later at the University of Bologna with Professor Righi. He was always absorbed in science, and experimented, holiday after holiday, on his father’s estate. He was precocious to an extraordinary degree, for in 1895, when only twenty-one, he had produced a wireless transmitting apparatus that he patented in Italy. Within a year he had taken out patents in England and in other European countries, and had proposed a wireless telegraph system to the English Post-Office Department. That Department, through Sir William Henry Preece, Engineer-in-Chief of Telegraphs, took up the subject, and reported very favorably on the Marconi System. Marconi himself, at the House of Commons, telegraphed by wireless across the Thames, a distance of 250 yards. In June, 1897, he sent a message nine miles, in July twelve miles, and in 1898 he succeeded in sending one across the English Channel to France, thirty-two miles. In 1901 he covered a space of 3,000 miles.
Let us now see what it was that Marconi had actually done.
Wireless signals are in reality wave motions in the magnetic forces of the earth, or, in other words, disturbances of those forces. They are sent out through this magnetic field, and follow the earth’s curvature, in the same way that tidal waves follow the ocean’s surface. Everywhere about us there is a sea of what science calls the ether, and the ether is constantly in a state of turmoil, because it is the medium through which energy, radiating from the sun, is carried to the earth and other planets. This energy is transmitted through the free ether in waves, which are known as electromagnetic waves. It was this fact that Professor Hertz discovered, and the waves are sometimes called the Hertzian waves. Light is one variety of wave motion, and heat another. The ether must be distinguished from the air, for science means by it a medium which exists everywhere and is to be regarded as permeating all space and all matter. The ether exists in a vacuum, for, although all the air may have been withdrawn, an object placed in a vacuum can still be seen from outside, and hence the wave motions of light are traveling through a space devoid of air.
Professor Hertz proved in 1888 that a spark, or disruptive discharge of electricity, caused electro-magnetic waves to radiate away in all directions through the ether. The waves acted exactly like ripples that radiate from a stone when it strikes the water. These Hertzian waves were found to travel with the same velocity as light, and would circle the world eight times in a second. As soon as the existence of these waves was known many scientists began to consider whether they could not be used for telegraphy. But the problem was a very difficult one. The questions were how to transmit the energy to a distance, and how to make a receiver that should be sensitive enough to be affected by it.
Let us picture a body of still water with a twig floating upon its surface. If a stone is thrown into the water ripples radiate in all directions, these waves becoming weaker as the circles they form become larger, or in other words as they grow more distant from the point where the stone struck the water. When the waves reach the floating twig they will move it, and when they cease the twig will be motionless again. Should there be grasses or rocks protruding up from the water the motion given to the twig by the waves would be lessened, or distorted, or changed in many ways, depending on the intervening object. Whether the waves will actually impart motion to the twig will depend on the force by which these waves were started and upon the lightness of the twig, or its sensitiveness to the ripples as they radiate. If the water were disturbed by some other force than the stone the twig would be moved by that other force, and the observer could not tell from what direction the motion had come, or how it had been caused. Applying this to wireless telegraphy one may say that a device must be used that will send out waves of a certain length, and that the receiver must be constructed so that it will respond only to waves of the length sent by that transmitter.
There must therefore be accurate tuning of the two instruments. Let a weight be fastened at the end of a spiral spring and then be struck. The weight will oscillate at a uniform rate, or so many times a minute. If this be held so that it strikes the water the movement of the spring will create a certain number of waves a minute. If now a second weight, attached to a second spring, be hung down into the water, the waves caused by the first will reach the second, and if the springs be alike the movements or oscillations will correspond. But if the springs were not alike, or if, in other words, the two instruments were not in tune, the wave motions would not be received and copied accurately. Therefore in wireless telegraphy the instrument that is to impart the motion to the electro-magnetic waves that fill the ether must be tuned in accord with the instrument that is to receive the motion of those waves.
The sending of the wireless message requires a source of production of the electro-magnetic waves. This is obtained by what is known as capacity, or in other words, the power that is possessed by any metal surface to retain a charge of electricity, and by inductance, procured when a constantly changing current is sent through a coil of wire. This capacity and inductance must be adjusted to give exactly the same frequency of motion to the waves, or the same oscillations, if the receiver that is tuned to vibrate to those waves is to receive that message accurately. The receiving station must have the means to intercept the waves, and then transform them again into electrical oscillations that shall correspond to those sent out from the transmitting station.
As early as 1844 Samuel F. B. Morse had succeeded in telegraphing without wires under the Susquehanna River, and in 1854 James Bowman Lindsay, a Scotchman, had sent a message a distance of two miles through water without wires. Sir William Henry Preece, by using an induced current, had telegraphed several miles without a connecting wire. But the discoveries made in regard to the Hertzian waves placed the subject on a different footing, and the possibility of an actual usable wireless telegraph was now looked at from a new view-point.
Professor Hertz had used a simple form of apparatus to obtain his free ether waves. A loop of wire, with the ends almost touching each other, had been his receiver, or detector. When he set his generator, or instrument to create the oscillations, in operation, and held the detector near it, he could see very minute electric sparks passing between the ends of the loop of wire. This proved the existence of the electro-magnetic waves.
In 1890 Professor Eduard Branly found that loose metallic filings became good conductors of electricity when there were electric oscillations at hand. He demonstrated this by placing the filings between metal plugs in a glass tube, and connecting this in circuit with a battery and electric indicator. Professor Oliver Lodge named this device of Branly’s a “coherer,” and when he found that it was more sensitive than the Hertz detector he combined it with the Hertz oscillator. This was in 1894, and the combination of oscillator and coherer actually formed the first real wireless set.
Wireless stations on shore are marked by very tall masts, which support a single wire, or a set of wires, which are known as the antenna. The antenna has electrical capacity, and when it is connected with the other apparatus needful to produce the oscillations it disturbs the earth’s magnetic field. For temporary service, as in the case of military operations, the antenna is frequently attached to captive balloons or kites, and so suspended high in air. On ships the antenna is fastened to the masts. The step that led to this addition was taken by Count Popoff in 1895, when he attached a vertical wire to one side of the coherer of the receiver of Professor Lodge, and connected the other side with the ground. He used this to learn the approach of thunder-storms.
With a knowledge of electro-magnetic waves, with a high-power oscillator, and a sensitive coherer, it remained for Marconi to connect an antenna to the transmitter, and thus secure a wide and practicable working field for the sending and receiving of his messages. This he did in 1896, and it was this addition that made the wireless telegraph of real use to men. Improvements in the transmitter and receiver have constantly increased the power of the invention, and have gradually allowed him to employ it over greater and greater distances.
With Marconi’s successful demonstrations of wireless in England its use at once began. The Trinity House installed a station at the East Goodwin Lighthouse, which communicated with shore and proved of the greatest value in preventing shipwrecks. The Marconi Wireless Telegraph Company was organized in 1897, and made agreements to erect coast stations for the Italian, Canadian, and Newfoundland governments, and for Lloyd’s. The great shipping lines established wireless stations on their vessels, and the antenna were soon to be seen on points of vantage along every coast. On December 12, 1901, Marconi in Newfoundland caught the message sent from Cornwall; on January 19, 1903, President Roosevelt sent the first “official” wireless message across the Atlantic to Edward VII, and in October, 1905, a message was sent from England across the mountains, valleys and cities of Europe to the battle-ship Renown, stationed at the entrance to the Suez Canal.he system of operating wireless telegraphy is in some respects similar to that of the ordinary telegraph. The Morse Code is largely used in America, and a modification of it, called the Continental Code, in Europe. When the wireless operator wishes to send a message to another station he “listens in,” as it is called, by connecting his receiving apparatus with the adjacent antenna and the ground. He has the telephone receiver attached to his ears. Next he adjusts his receiving circuits for a number of wave lengths. If he catches no signals in his telephone receiver he understands that no messages are being sent within his area. Then he “throws in” the transmitting apparatus, which automatically disconnects the receiving end. He gives the letters that stand for the station with which he wants to communicate, and adds the letters of his own station. He does this a number of times, to insure the other station picking up the call. Then he “listens in,” and if he receives the clicks that show that the other station has heard him he is ready to establish regular telegraphic communication.
A number of distant stations may be sending messages simultaneously. In that case the operator tunes his instrument, or in other words adjusts his apparatus to suit the wave length of the station with which he wishes to communicate. In this way he “tunes out” the other messages, and receives only the one he wants. If, however, the stations that are sending simultaneously happen to be situated near together, as in the case of several vessels near a shore station, the operator is often unable to do this “tuning out,” and must try to catch the message he wishes by the sound of the “spark” of the transmitting station, if he can in any way distinguish it from the “sparks” of the other messages.
There are several ways of determining when the two circuits are in tune. One is to insert a hot-wire current meter between the antenna and the inductance, which indicates the strength of the oscillatory current that has been established. A maximum reading can then be made by manipulating the flexible connections, and this will show whether the two circuits are in accord. The other method is by using a device that indicates the wave length. This measures the frequency of one circuit, and then the other circuit can be adjusted to give a corresponding wave length. The larger the antenna the longer will be the wave length and the greater the power of the apparatus. It is usual to employ a short wave length for low-power, short-distance equipments, and a long wave length for the high-power, long-distance stations.
Wireless telegraphy has already proved itself of the greatest value on the ocean. It has sent news of storms and wrecks across tossing seas and brought rescue to scores of voyagers. Ships may now keep in constant communication with their offices on shore. The great lines send Marconigrams to each other in mid-ocean, and publish daily papers giving the latest news of the whole world. Greater distances have so far been covered over water than over land, but this branch of the service is being rapidly developed, and it must prove in time of the greatest value across deserts and wild countries, where a regular telegraph service would be impracticable. In such a country as Alaska, where there are constant heavy sleet and snow storms, the wireless should prove invaluable.
The telegraph and cable companies did their best to ignore the claims of the wireless systems, but they have been compelled to acknowledge them at last. Rival companies have sprung up, using slightly different varieties of apparatus. Each of the big companies that were ready to compete with the Marconi Company by 1906, the German Telefunken Company, the American National Electric Signaling Company, the American De Forest Company, and the British Lodge-Muirhead Wireless Syndicate, had certain peculiar advantages over the others. The laws relating to the uses of wireless, and especially the rights of governments to the sole use of the systems in case of war, are in a confused condition, but eventually order must come from this chaos as it did in the history of the telephone and telegraph.
Wireless has brought the possibility of communication between any two individuals, no matter where they may be situated, within the realm of fact. A severing of communication with any part of the world will be impossible. Storms and earthquakes that destroy telegraph systems, enemies that cut submarine cables, cannot prevent the sending of Marconigrams. The African explorer and the Polar adventurer can each talk with his countrymen. The use of this agency is still in its earliest youth, but it has already done so much that it is impossible to say to what a stature it may grow. It should cut down the rates for using wire and cable systems, and ultimately place the means of communicating directly with any one on land or sea within the reach of every man. All the world’s information will be at the instant disposal of whomsoever needs it, and all this is due to those electro-magnetic waves that permeate the ether, waiting to be put into service at the touch of man.
Samuel F.B. Morse (born April 27, 1791, Charlestown, Massachusetts, U.S.—died April 2, 1872, New York, New York) was an American painter and inventor who developed an electric telegraph (1832–35). In 1838 he and his friend Alfred Vail developed the Morse Code.
He was the son of the distinguished geographer and Congregational clergyman Jeddah Morse. From Phillips Academy in Andover, Massachusetts, where he had been an unsteady and eccentric student, his parents sent him to Yale College (now Yale University) in New Haven, Connecticut. Although he was an indifferent scholar, his interest was aroused by lectures on the then little-understood subject of electricity. To the distress of his austere parents, he also enjoyed painting miniature portraits.
After graduating from Yale in 1810, Morse became a clerk for a Boston book publisher. But painting continued to be his main interest, and in 1811 his parents helped him go to England in order to study that art with American painter Washington Allston. During the War of 1812, between Great Britain and the United States, Morse reacted to the English contempt for Americans by becoming passionately pro-American. Like the majority of Americans of his time, however, he accepted English artistic standards, including the “historical” style of painting—the Romantic portrayal of legends and historical events with personalities gracing the foreground in grand poses and brilliant colour.When, on his return home in 1815, Morse found that Americans did not appreciate his historical canvases, he reluctantly took up portraiture again to earn a living. He began as an itinerant painter in New England, New York, and South Carolina. After 1825, on settling in New York City, he painted some of the finest portraits ever done by an American artist. He combined technical competence and a bold rendering of his subjects’ character with a touch of the Romanticism he had imbibed in England.
Although often poor during those early years, Morse was sociable and at home with intellectuals, the wealthy, the religiously orthodox, and the politically conservative. In addition, he possessed the gift of friendship. Among his friends in his middle years were a French hero of the American Revolution, the marquis de Lafayette, whose attempts to promote liberal reform in Europe Morse ardently endorsed, and the novelist James Fennimore Cooper. Morse and Cooper shared several traits: both were ardent U.S. republicans, though both had aristocratic social tastes, and both suffered from the American preference for European art.
Morse also had the gift of leadership. As part of a campaign against the licentiousness of the theatre, he helped launch, in 1827, the New York Journal of Commerce, which refused theatre advertisements. He also was a founder of the National Academy of Design, organized to increase U.S. respect for painters, and was its first president from 1826 to 1845.In 1832, while returning by ship from studying art in Europe, Morse conceived the idea of an electric telegraph as the result of hearing a conversation about the newly discovered electromagnet. Although the idea of an electric telegraph had been put forward in 1753 and electric telegraphs had been used to send messages over short distances as early as 1774, Morse believed that his was the first such proposal. He probably made his first working model by 1835.Meanwhile, Morse was still devoting most of his time to painting, teaching art at the University of the City of New York (later New York University), and to politics (he ran on anti-immigrant and anti-Roman Catholic tickets for mayor of New York in 1836 and 1841). But by 1837 he had turned his full attention to the new invention. A colleague at the university, chemist Leonard Gale, introduced Morse to Joseph Henry’s work on electromagnetism. The powerful electromagnets that Henry had devised allowed Morse to send messages over 16 km (10 miles) of wire, a much longer distance than the 12 meters (40 feet) over which his first model could transmit. A friend, Alfred Vail, offered to provide materials and labor to build models in his family’s ironworks in Morristown, New Jersey. Gale and Vail became partners in Morse’s telegraph rights. By 1838 he and Vail had developed the system of dots and dashes that became known throughout the world as the Morse code. In 1838, while unsuccessfully attempting to interest Congress in building a telegraph line, he acquired Maine Congressman F.O.J. Smith as an additional partner. After failing to organize the construction of a Morse line in Europe, Morse alone among his partners persevered in promoting the telegraph, and in 1843 he was finally able to obtain financial support from Congress for the first telegraph line in the United States, from Baltimore to Washington. In 1844 the line was completed, and on May 24 he sent the first message, “What hath God wrought.”
Morse was immediately involved in legal claims by his partners and by rival inventors. A natural controversialist like his father, he fought vigorously in this and other controversies, such as those in art with painter John Trumbull, in religion with Unitarians and Roman Catholics, in politics with the Irish and abolitionists, and in daguerreotypy—of which he was one of the first practitioners in America—with Louis-Jacques-Mandé Daguerre’s pupil, François Gouraud. The legal battles over the telegraph culminated in an 1854 U.S. Supreme Court decision that established his patent rights. As telegraph lines lengthened on both sides of the Atlantic, his wealth and fame increased. By 1847 Morse had bought Locust Grove, an estate overlooking the Hudson River near Poughkeepsie, New York, where, early in the 1850s, he built an Italian villa-style mansion. He spent his summers there with his large family of children and grandchildren, returning each winter season to his brownstone home in New York City.
In his old age, Morse, a patriarch with a flowing beard, became a philanthropist. He gave generously to Vassar College, of which he was a founder and trustee; to his alma mater, Yale College; and to churches, theological seminaries, Bible societies, mission societies, and temperance societies, as well as to poor artists.
Even during Morse’s own lifetime, the world was much changed by the telegraph. In the decades after his death in 1872, his fame as an inventor was obscured by the invention of the telephone, radio, television, and the Internet, while his reputation as an artist has grown. At one time he did not wish to be remembered as a portrait painter, but his powerful and sensitive portraits, among them those of Lafayette, the American writer William Cullen Bryant, and other prominent men, have been exhibited throughout the United States. The number of Morse telegraphic operators has decreased sharply, but his memory is perpetuated by the Morse Telegraph Club (1942), an association dedicated to the history of telegraphy. His 1837 telegraph instrument is preserved by the Smithsonian Institution’s National Museum of American History in Washington, D.C., while his estate, Locust Grove, is now designated a national historic landmark.

The present section of this volume deals with polyphase currents, and the inventions by Mr. Tesla, made known thus far, in which he has embodied one feature or another of the broad principle of rotating field poles or resultant attraction exerted on the armature. It is needless to remind electricians of the great interest aroused by the first enunciation of the rotating field principle, or to dwell upon the importance of the advance from a single alternating current, to methods and apparatus which deal with more than one. Simply prefacing the consideration here attempted of the subject, with the remark that in nowise is the object of this volume of a polemic or controversial nature, it may be pointed out that Mr. Tesla's work has not at all been fully understood or realized up to date. To many readers, it is believed, the analysis of what he has done in this department will be a revelation, while it will at the same time illustrate the beautiful flexibility and range of the principles involved. It will be seen that, as just suggested, Mr. Tesla did not stop short at a mere rotating field, but dealt broadly with the shifting of the resultant attraction of the magnets. It will be seen that he went on to evolve the "multiphase" system with many ramifications and turns; that he showed the broad idea of motors employing currents of differing phase in the armature with direct currents in the field; that he first described and worked out the idea of an armature with a body of iron and coils closed upon themselves; that he worked out both synchronizing and torque motors; that he explained and illustrated how machines of ordinary construction might be adapted to his system; that he employed condensers in field and armature circuits, and went to the bottom of the fundamental principles, testing, approving or rejecting, it would appear, every detail that inventive ingenuity could hit upon.[Pg 8]
Now that opinion is turning so emphatically in favor of lower frequencies, it deserves special note that Mr. Tesla early recognized the importance of the low frequency feature in motor work. In fact his first motors exhibited publicly—and which, as Prof. Anthony showed in his tests in the winter of 1887-8, were the equal of direct current motors in efficiency, output and starting torque—were of the low frequency type. The necessity arising, however, to utilize these motors in connection with the existing high frequency circuits, our survey reveals in an interesting manner Mr. Tesla's fertility of resource in this direction. But that, after exhausting all the possibilities of this field, Mr. Tesla returns to low frequencies, and insists on the superiority of his polyphase system in alternating current distribution, need not at all surprise us, in view of the strength of his convictions, so often expressed, on this subject. This is, indeed, significant, and may be regarded as indicative of the probable development next to be witnessed.
Incidental reference has been made to the efficiency of rotating field motors, a matter of much importance, though it is not the intention to dwell upon it here. Prof. Anthony in his remarks before the American Institute of Electrical Engineers, in May, 1888, on the two small Tesla motors then shown, which he had tested, stated that one gave an efficiency of about 50 per cent. and the other a little over sixty per cent. In 1889, some tests were reported from Pittsburgh, made by Mr. Tesla and Mr. Albert Schmid, on motors up to 10 h. p. and weighing about 850 pounds. These machines showed an efficiency of nearly 90 per cent. With some larger motors it was then found practicable to obtain an efficiency, with the three wire system, up to as high as 94 and 95 per cent. These interesting figures, which, of course, might be supplemented by others more elaborate and of later date, are cited to show that the efficiency of the system has not had to wait until the present late day for any demonstration of its commercial usefulness. An invention is none the less beautiful because it may lack utility, but it must be a pleasure to any inventor to know that the ideas he is advancing are fraught with substantial benefits to the public.
Pythagoras is often referred to as the first pure mathematician. He was born on the island of Samos, Greece in 569 BC. Various writings place his death between 500 BC and 475 BC in Metapontum, Lucania, Italy. His father, Mnesarchus, was a gem merchant. His mother's name was Pythais. Pythagoras had two or three brothers.
Some historians say that Pythagoras was married to a woman named Theano and had a daughter Damo, and a son named Telauges, who succeeded Pythagoras as a teacher and possibly taught Empedocles. Others say that Theano was one of his students, not his wife, and say that Pythagoras never married and had no children.
Pythagoras was well educated, and he played the lyre throughout his lifetime, knew poetry and recited Homer. He was interested in mathematics, philosophy, astronomy and music, and was greatly influenced by Pherekydes (philosophy), Thales (mathematics and astronomy) and Anaximander (philosophy, geometry).
Pythagoras left Samos for Egypt in about 535 B.C. to study with the priests in the temples. Many of the practices of the society he created later in Italy can be traced to the beliefs of Egyptian priests, such as the codes of secrecy, striving for purity, and refusal to eat beans or to wear animal skins as clothing.
Ten years later, when Persia invaded Egypt, Pythagoras was taken prisoner and sent to Babylon (in what is now Iraq), where he met the Magi, priests who taught him sacred rites. Iamblichus (250-330 AD), a Syrian philosopher, wrote about Pythagoras, "He also reached the acme of perfection in arithmetic and music and the other mathematical sciences taught by the Babylonians..."
In 520 BC, Pythagoras, now a free man, left Babylon and returned to Samos, and sometime later began a school called The Semicircle. His methods of teaching were not popular with the leaders of Samos, and their desire for him to become involved in politics did not appeal to him, so he left.
Pythagoras settled in Crotona, a Greek colony in southern Italy, about 518 BC, and founded a philosophical and religious school where his many followers lived and worked. The Pythagoreans lived by rules of behavior, including when they spoke, what they wore and what they ate. Pythagoras was the Master of the society, and the followers, both men and women, who also lived there, were known as mathematical. They had no personal possessions and were vegetarians. Another group of followers who lived apart from the school were allowed to have personal possessions and were not expected to be vegetarians. They all worked communally on discoveries and theories. Pythagoras believed:
• All things are numbers. Mathematics is the basis for everything, and geometry is the highest form of mathematical studies. The physical world can understood through mathematics.
• The soul resides in the brain, and is immortal. It moves from one being to another, sometimes from a human into an animal, through a series of reincarnations called transmigration until it becomes pure. Pythagoras believed that both mathematics and music could purify.
• Numbers have personalities, characteristics, strengths and weaknesses.
• The world depends upon the interaction of opposites, such as male and female, lightness and darkness, warm and cold, dry and moist, light and heavy, fast and slow.
• Certain symbols have a mystical significance.
• All members of the society should observe strict loyalty and secrecy.
Because of the strict secrecy among the members of Pythagoras' society, and the fact that they shared ideas and intellectual discoveries within the group and did not give individuals credit, it is difficult to be certain whether all the theorems attributed to Pythagoras were originally his, or whether they came from the communal society of the Pythagoreans. Some of the students of Pythagoras eventually wrote down the theories, teachings and discoveries of the group, but the Pythagoreans always gave credit to Pythagoras as the Master for:
1. The sum of the angles of a triangle is equal to two right angles.
2. The theorem of Pythagoras - for a right-angled triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides. The Babylonians understood this 1000 years earlier, but Pythagoras proved it.
3. Constructing figures of a given area and geometrical algebra. For example they solved various equations by geometrical means.
4. The discovery of irrational numbers is attributed to the Pythagoreans, but seems unlikely to have been the idea of Pythagoras because it does not align with his philosophy the all things are numbers, since number to him meant the ratio of two whole numbers.
5. The five regular solids (tetrahedron, cube, octahedron, icosahedron, dodecahedron). It is believed that Pythagoras knew how to construct the first three but not last two.
6. Pythagoras taught that Earth was a sphere in the center of the Kosmos (Universe), that the planets, stars, and the universe were spherical because the sphere was the most perfect solid figure. He also taught that the paths of the planets were circular. Pythagoras recognized that the morning star was the same as the evening star, Venus.
Pythagoras studied odd and even numbers, triangular numbers, and perfect numbers. Pythagoreans contributed to our understanding of angles, triangles, areas, proportion, polygons, and polyhedra.
Pythagoras also related music to mathematics. He had long played the seven string lyre, and learned how harmonious the vibrating strings sounded when the lengths of the strings were proportional to whole numbers, such as 2:1, 3:2, 4:3. Pythagoreans also realized that this knowledge could be applied to other musical instruments.
The reports of Pythagoras' death are varied. He is said to have been killed by an angry mob, to have been caught up in a war between the Agrigentum and the Syracusans and killed by the Syracusans, or been burned out of his school in Crotona and then went to Metapontum where he starved himself to death. At least two of the stories include a scene where Pythagoras refuses to trample a crop of bean plants in order to escape, and because of this, he is caught.
The Pythagorean Theorem is a cornerstone of mathematics, and continues to be so interesting to mathematicians that there are more than 400 different proofs of the theorem, including an original proof by President Garfield.

KFC, the fast-food restaurant chain formerly known as Kentucky Fried Chicken, is moving its corporate headquarters in the US from Louisville in Kentucky to Plano in Texas, according to a statement from its parent company, Yum Brands.
About 100 corporate employees and dozens more remote workers will be required to move and will receive relocation support.
The decision by Yum Brands is part of a plan to have two headquarters for its main brands — KFC and Pizza Hut will be headquartered in Plano, while Taco Bell and Habit Burger & Grill will remain in Irvine, California.
In recent years, many companies have relocated to Texas attracted by the state's lower taxes and business-friendly policies."These changes position us for sustainable growth and will help us better serve our customers, employees, franchisees and shareholders," said David Gibbs, the chief executive of Yum Brands in the company's statement.
Yum also expressed hope the plan will boost collaboration between its employees and brands.
The statement added that Yum will be maintaining it corporate offices as well as the KFC Foundation in Louisville.
The governor of the state of Kentucky, Andy Beshea, has criticised the move to relocate KFC's headquarters, according to a statement given to the Associated Press.
"I am disappointed by this decision and believe the company's founder would be, too," Mr Beshear reportedly said.
"This company's name starts with Kentucky, and it has marketed our state's heritage and culture in the sale of its product."
KFC's history in the state dates back to the 1930s, when its founder Colonel Harland Sanders began selling fried chicken at a service station in Corbin.
Today, Sanders' face is emblazoned on the shop fronts of more than 24,000 KFC restaurants in over 145 countries and territories around the world.
Since the pandemic, many US companies have moved their headquarters. According to a report by real estate services firm CBRE, Austin and other Texan cities have been particularly successful due to the state's business-friendly environment.
n the credulous twaddle of an essay on the Lost Arts one may generally find the telescope ascribed to far antiquity. In place of evidence there is vague allusion of classical times or wild flights of fancy like one which argued from the Scriptural statement that Satan took up Christ into a high mountain and showed him all the kingdoms of the earth, that the Devil had a telescope—bad optics and worse theology.
In point of fact there is not any indication that either in classical times, or in the black thousand years of hopeless ignorance that followed the fall of Roman civilization, was there any knowledge of optical instruments worth mentioning.
The peoples that tended their flocks by night in the East alone kept alive the knowledge of astronomy, and very gradually, with the revival of learning, came the spirit of experiment that led to the invention of aids to man’s natural powers.
The lineage of the telescope runs unmistakably back to spectacles, and these have an honorable history extending over more than six centuries to the early and fruitful days of the Renaissance.
That their origin was in Italy near the end of the thirteenth century admits of little doubt. A Florentine manuscript letter of 1289 refers to “Those glasses they call spectacles, lately invented, to the great advantage of poor old men when their sight grows weak,” and in 1305 Giordano da Rivalto refers to them as dating back about twenty years.
Finally, in the church of Santa Maria Maggiore in Florence lay buried Salvino d’Amarto degli Armati, (obiit 1317) under an epitaph, now disappeared, ascribing to him the invention of spectacles. W. B. Carpenter, F. R. S., states that the inventor tried to keep the valuable secret to himself, but it was discovered and published before his death. At all events the discovery moved swiftly. By the early fourteenth century it had spread to the Low Countries where it was destined to lead to great results, and presently was common knowledge over all civilized Europe.
It was three hundred years, however, between spectacles and the combination of spectacle lenses into a telescope, a lapse of time which to some investigators has seemed altogether mysterious. The ophthalmological facts lead to a simple explanation. The first spectacles were for the relief of presbyopia, the common and lamentable affection of advancing years, and for this purpose convex lenses of very moderate power sufficed, nor was material variation in power necessary. Glasses having a uniform focus of a foot and a half or thereabouts would serve every practical purpose, but would be no material for telescopes.
Myopia was little known, its acquired form being rare in a period of general illiteracy, and glasses for its correction, especially as regards its higher degrees, probably came slowly and were in very small demand, so that the chance of an optical craftsman having in hand the ordinary convex lenses and those of strong negative curvature was altogether remote. Indeed it was only in 1575 that Maurolycus published a clear description of myopia and hypermetropia with the appropriate treatment by the use of concave and convex lenses. Until both of these, in quite various powers, were available, there was small chance of hitting upon an instrument that required their use in a highly special combination.
At all events there is no definite trace of the discovery of telescopic vision until 1608 and the inventor of record is unquestionably one Jan Lippershey, a spectacle maker of Middelburg in Zeeland, a native of Wesel. On Oct. 2, 1608 the States-General took under consideration a petition which had been presented by Lippershey for a 30-year patent to the exclusive right of manufacture of an instrument for seeing at a distance, or for a suitable pension, under the condition that he should make the instrument only for his country’s service.
The States General pricked up its ears and promptly appointed on Oct. 4 a committee to test the new instrument from a tower of Prince Maurice’s palace, allotting 900 florins for the purchase of the invention should it prove good. On the 6th the committee reported favorably and the Assembly agreed to give Lippershey 900 florins for his instrument, but desired that it be arranged for use with both eyes.
Lippershey therefore pushed forward to the binocular form and two months later, Dec. 9, he announced his success. On the 15th the new instrument was examined and pronounced good, and the Assembly ordered two more binoculars, of rock crystal, at the same price. They denied a patent on the ground that the invention was known to others, but paid Lippershey liberally as a sort of retainer to secure his exclusive services to the State. In fact even the French Ambassador, wishing to obtain an instrument from him for his King, had to secure the necessary authorization from the States-General.
