"At last we leave the territory of theory and experiment and come to that of practice. 'The merit of inventing the modern telegraph, and applying it on a large scale for public use, is, beyond all question, due to Professor Morse of the United States.' So writes Sir David Brewster, and the best authorities on the question substantially agree with him. ... Leaving for future consideration Morse's telegraph, which was not introduced until five years after the time when he was impressed with the notion of its feasibility, we may mention the telegraph of Gauss and Weber of Göttingen. In 1833, they erected a telegraphic wire between the Astronomical and Magnetical Observatory of Göttingen, and the Physical Cabinet of the University, for the purpose of carrying intelligence from the one locality to the other. To these great philosophers, however, rather the theory than the practice of Electric Telegraphy was indebted. Their apparatus was so improved as to be almost a new invention by Steinheil of Munich, who, in 1837 ... succeeded in sending a current from one end to the other of a wire 36,000 feet in length, the action of which caused two needles to vibrate from side to side, and strike a bell at each movement. To Steinheil the honour is due of having discovered the important and extraordinary fact that the earth might be used as a part of the circuit of an electric current. The introduction of the Electric Telegraph into England dates from the same year as that in which Steinheil's experiments took place. William Fothergill Cooke, a gentleman who held a commission in the Indian army, returned from India on leave of absence, and afterwards, because of his bad health, resigned his commission, and went to Heidelberg to study anatomy. In 1836, Professor Mönke, of Heidelberg, exhibited an electro-telegraphic experiment, 'in which electric currents, passing along a conducting wire, conveyed signals to a distant station by the deflexion of a magnetic needle enclosed in Schweigger's galvanometer or multiplier.' ... Cooke was so struck with this experiment, that he immediately resolved to apply it to purposes of higher utility than the illustration of a lecture. ... In a short time he produced two telegraphs of different construction. When his plans were completed, he came to England, and in February, 1837, having consulted Faraday and Dr. Roget on the construction of the electric-magnet employed in a part of his apparatus, the latter gentleman advised him to apply to Professor Wheatstone. ... The result of the meeting of Cooke and Wheatstone was that they resolved to unite their several discoveries; and in the month of May 1837, they took out their first patent 'for improvements in giving signals and sounding alarms in distant places by means of electric currents transmitted through metallic circuits.' ... By-and-by, as might probably have been anticipated, difficulties arose between Cooke and Wheatstone, as to whom the main credit of introducing the Electric Telegraph into England was due. Mr. Cooke accused Wheatstone (with a certain amount of justice, it should seem) of entirely ignoring his claims; and in doing so Mr. Cooke appears to have rather exaggerated his own services. Most will readily agree to the wise words of Mr. Sabine: "It was once a popular fallacy in England that Messrs. Cooke and Wheatstone were the original inventors of the Electric Telegraph. The Electric Telegraph had, properly speaking, no inventor; it grew up as we have seen little by little."

"In the latter part of the year 1832, Samuel F. B. Morse, an American artist, while on a voyage from France to the United States, conceived the idea of an electromagnetic telegraph which should consist of the following parts, viz: A single circuit of conductors from some suitable generator of electricity; a system of signs, consisting of dots or points and spaces to represent numerals; a method of causing the electricity to mark or imprint these signs upon a strip or ribbon of paper by the mechanical action of an electro-magnet operating upon the paper by means of a lever, armed at one end with a pen or pencil; and a method of moving the paper ribbon at a uniform rate by means of clock-work to receive the characters. ... In the autumn of the year 1835 he constructed the first rude working model of his invention. ... The first public exhibition ... was on the 2d of September, 1837, on which occasion the marking was successfully effected through one third of a mile of wire. Immediately afterwards a recording instrument was constructed ... which was subsequently employed upon the first experimental line between Washington and Baltimore. This line was constructed in 1843-44 under an appropriation by Congress, and was completed by May of the latter year. On the 27th of that month the first despatch was transmitted from Washington to Baltimore. ... The experimental line was originally constructed with two wires, as Morse was not at that time acquainted with the discovery of Steinheil, that the earth might be used to complete the circuit. {774} Accident, however, soon demonstrated this fact. ... The following year (1845) telegraph lines began to be built over other routes. ... In October, 1851, a convention of deputies from the German States of Austria, Prussia, Bavaria, Würtemberg and Saxony, met at Vienna, for the purpose of establishing a common and uniform telegraphic system, under the name of the German-Austrian Telegraph Union. The various systems of telegraphy then in use were subjected to the most thorough examination and discussion. The convention decided with great unanimity that the Morse system was practically far superior to all others, and it was accordingly adopted. Prof. Steinheil, although himself ... the inventor of a telegraphic system, with a magnanimity that does him high honor, strongly urged upon the convention the adoption of the American system." ... The first of the printing telegraphs was patented in the United States by Royal E. House, in 1846. The Hughes printing telegraph, a remarkable piece of mechanism, was patented by David E. Hughes, of Kentucky, in 1855. A system known as the automatic method, in which the signals representing letters are transmitted over the line through the instrumentality of mechanism, was originated by Alexander Bain of Edinburgh, whose first patents were taken out in 1846. An autographic telegraph, transmitting despatches in the reproduced hand-writing of the sender, was brought out in 1850, by F. C. Bakewell, of London. The same result was afterwards accomplished with variations of method by Charles Cros, of Paris, Abbé Caseli, of Florence, and others; but none of these inventions has been extensively used. "The possibility of making use of a single wire for the simultaneous transmission of two or more communications seems to have first suggested itself to Moses G. Farmer, of Boston, about the year 1852." The problem was first solved with partial success by Dr. Gintl, on the line between Prague and Vienna, in 1853, but more perfectly by Carl Frischen, of Hanover, in the following year. Other inventors followed in the same field, among them Thomas A. Edison, of New Jersey, who was led by his experiments finally, in 1874 to devise a system "which was destined to furnish the basis of the first practical solution of the curious and interesting problem of quadruplex telegraphy."
