Introduction
After the experiments of Franklin that did so much to advance the study of electrical phenomena and to suggest practical applications of electricity, physicists in all countries occupied themselves with investigations along lines marked out by the American philosopher. In 1749 Franklin devised the lightning-rod. But notwithstanding the labors of many investigators, it was more than fifty years before any other practical discovery or invention in electricity was brought into general use. The first great achievement of the kind was Morse’s improvement of the electric telegraph. That Morse’s fellow-countryman, Joseph Henry, chiefly prepared the way for that triumph, the following account, with just emphasis, demonstrates.

Among the European scientists and inventors to whom both Henry and Morse were indebted was the French electrician, André Marie Ampère (1775-1836), whose name (ampère) has been given to the practical unit of electric-current strength. Ampère was the first and is the most famous investigator in electrodynamics. He also invented a telegraphic arrangement in which he used the magnetic needle and coil and the galvanic battery. Others, in the latter part of the eighteenth century and the earlier years of the nineteenth, devised similar arrangements. But no strictly electromagnetic apparatus for telegraphic signalling was put to successful use until 1836, when, in England, Charles Wheatstone, who is commonly regarded as the first inventor of practical electric telegraphy, constructed an apparatus whereby thirty signals were transmitted through nearly four miles of wire. From 1837 to 1843 he had as an associate William Fothergill Cooke and the two worked together to develop the electric telegraph. They afterward quarrelled over their respective claims to credit but in 1838-1841 telegraph lines secured by their patents were set up on the Great Western and two other English railways.

Meanwhile other inventors were still working for the same results, in many parts of the world and it has been significantly said that “the electric telegraph had, properly speaking, no inventor; it grew up little by little.” Nevertheless with respect to the distinctive character of Morse’s improvements and his title to a peculiar place among those through whose labors the electric telegraph “grew,” there can be no question.

Alonzo B. Cornell, son of the founder of Cornell University, at one time Governor of New York, was intimately connected with electrical and telegraphic affairs for many years; therefore on the subject here presented he speaks with professional authority. His father was the first builder of the Morse telegraphs.

Time: 1844

During the early years of the nineteenth century but slight advance was made in the development of electrical science, although there were many persons both here and abroad engaged in experimental work and there was considerable increase of literature bearing upon the subject. It was reserved for another illustrious American to accomplish the next important and decisive step in the pathway of progress. In 1828 Joseph Henry, then professor of physics at the Albany Academy, afterward a professor at Princeton and subsequently for many years secretary of the Smithsonian Institution at Washington, made the highly important discovery that by winding a plain iron core with many layers of insulated wire, through which the electric current was passed, he could at pleasure charge and discharge the iron core with magnetic power. Thus Henry produced the electromagnet which was the beginning of the mastery by man of the subtle fluid. He also discovered that the intensity and power of the electric current were materially augmented by increasing the number of the series of battery plates without increasing the quantity of metal used in their construction.

These discoveries of Henry were, beyond all question, the most important in real and intrinsic value ever made in the progress of electric science, as they form the solid basis upon which all subsequent inventors have been enabled to accomplish successful results in their various fields of endeavor. It is conceded by all familiar with the history of electrical progress that the name of Professor Joseph Henry is to be honored and cherished as one of the very foremost of scientific discoverers of any age or country and it must remain a cause of sincere and permanent regret that of all the fabulous wealth that has resulted from the advancement of electrical science, this modest and unselfish inventor should have passed hence without ever having realized any substantial reward for his great work. Not only so but he was never awarded the appropriate acknowledgment to which he was so eminently entitled for the inestimable benefits his discoveries conferred upon his countrymen and upon the world at large.

The possibility of utilizing Professor Henry’s electromagnet for the purpose of transmitting intelligence to a distant point was conceived by still another American, Professor Samuel Finley Breese Morse, of New York, [Footnote: He was born in Charlestown, Massachusetts, April 27, 1791. — ED.] during his passage on board the packet-ship Sully, from Havre to New York, in the winter of 1832. Incidental discussions between himself and Doctor Jackson, a fellow-passenger, in reference to recent electrical improvements on both sides of the Atlantic, led Morse to the conclusion that intelligence might be instantaneously transmitted over a metallic circuit to a distant point and he thereupon determined to devote himself to the solution of the problem involved. The following day he exhibited a rough sketch of a plan for recording electric impulses necessary to convey and express intelligence. He pursued the subject with great devotion during the remainder of the voyage and after arrival in New York began the construction of the necessary apparatus to accomplish his purpose.

Morse was by profession a portrait painter of more than ordinary merit and was obliged to continue his artistic labors for a livelihood. He was a graduate of Yale College, where his attention had first been attracted to electrical experiments. He was thus, in a measure, prepared for carrying forward the important work he had undertaken and pursued his labors with great assiduity. Devoting every spare moment to the pursuit of his object, which was attained but slowly by reason of his lack of mechanical skill and ingenuity, not until 1837 had he so far succeeded in his efforts as to be prepared to make application for letters-patent to enable him to secure and protect his rights of invention in the electromagnetic telegraph.

In explanation of the slow progress of his experimental work, Professor Morse, in writing to a friend, said: “Up to the autumn of 1837 my telegraphic apparatus existed in so rude a form that I felt reluctance to have it seen. My means were very limited, so limited as to preclude the possibility of constructing an apparatus of such mechanical finish as to warrant my success in venturing upon its public exhibition. I had no wish to expose to ridicule the representative of so many hours of laborious thought. Prior to the summer of 1837 I depended upon my pencil for subsistence. Indeed, so straitened were my circumstances that in order to save time to carry out my invention and to economize my scanty means I had for months lodged and eaten in my studio, procuring food in small quantities from some grocery and preparing it myself. To conceal from my friends the stinted manner in which I lived, I was in the habit of bringing food to my room in the evenings; and this was my mode of life for many years.”

After the continuance of this heroic struggle for more than five years, Morse found himself compelled to seek the aid of more accomplished mechanical skill than he possessed, to perfect his apparatus and was obliged to surrender a quarter interest in his invention in order to obtain pecuniary aid for this purpose.

Having thus succeeded in obtaining, at such serious sacrifice, the requisite financial assistance to enable him to perfect the mechanism necessary to demonstrate his invention, Professor Morse lost no time in completing his apparatus and presenting it for public inspection. On January 6, 1838, he first operated his system successfully, over a wire three miles long, in the presence of a number of personal friends, at Morristown, New Jersey. In the following month he made a similar exhibition before the faculty of the New York University, which was an occasion of much interest among the scientists of the metropolis.

Shortly thereafter the apparatus was taken to Philadelphia and exhibited at the Franklin Institute, where he received the highest commendation from the committee of science and arts, with a strong expression in favor of government aid for the purpose of demonstrating the practical usefulness of the system.

From Philadelphia, Morse removed his apparatus to Washington, where he was permitted to demonstrate its operation before President Van Buren and his Cabinet. Foreign ministers and members of both Houses of Congress, as well, also, as prominent citizens, were invited to attend the exhibition and manifested much interest in the novelty of the invention. A bill was introduced in Congress making an appropriation of thirty thousand dollars for the purpose of providing for the erection of an experimental line of telegraph between Washington and Baltimore, to illustrate, by practical use, its general utility. The bill was in good time favorably reported from the committee on commerce but made no further progress in that Congress. Similar bills were subsequently introduced and diligently supported in each succeeding Congress but it was not until the very closing hour of the expiring session of 1843 that the necessary enactment was effected and the appropriation secured.
