Famous Men of Science

by Sarah Knowles Bolton

Electricity had been known and studied since early times. It had been ascertained that the electric force could be stored up, as in the Leyden jar, and that it could be conducted through long metallic wires. The discovery of the Voltaic pile, or battery, in 1800, gave a great impetus to the study. Oersted of Copenhagen found that the position of the magnetic needle may be changed by the electric current, and that a magnet will induce electricity in a coil of wire. Schweigger of Halle discovered that "the deflection of the needle may be increased by coiling an insulated wire in a series of ovals or flat rings, compactly disposed, in a loop, and conducting the current around the needle from end to end." Ampère developed the theory of electro-magnetism, and proposed to the French Academy in 1820 a plan for a telegraph, in which there was to be a needle for each letter.

In 1827 Morse had listened to a course of lectures, given by Prof. James Freeman Dana, upon these matters, so that the subject was still fresh in his mind when he crossed the ocean in the Sully. Prof. Joseph Henry's important discoveries were also well known.

Says Prof. E. N. Horsford of Cambridge, Mass., in the admirable life of Morse written by Dr. Samuel Irenæus Prime: "He knew generally, when he stepped on board the Sully, in 1832, that a soft-iron horseshoe-shaped bar of iron could be rendered magnetic while a current of galvanic electricity was passing through a wire wound round it; and he knew that electricity had been transmitted, apparently instantaneously, through wires of great length, by Franklin and others.... In the leisure of ship-life the idea of a recording electric telegraph seized Professor Morse's mind, and he gave expression to his conviction that it was possible. As it was possible to dispatch and to arrest the current, he conceived that some device could be found for compelling it to manifest itself by this intermittent action, and produce a record.

"He knew, for he had witnessed it years before, that by means of a battery and an electro-magnet reciprocal motion could be produced. He knew that the force which produced it could be transmitted along a wire. He believed that the battery current could be made, through an electro-magnet, to produce physical effects at a distance. He saw in his mind's eye the existence of an agent and a medium by which reciprocal motion could be not only produced, but controlled, at a distance. The question that addressed itself to him at the outset was naturally this: 'How can I make use of the simple up-and-down motion of opening and closing a circuit to write an intelligible message at one end of a wire, and at the same time print it at the other?'...

"Like many a kindred work of genius, it was in nothing more wonderful than in its simplicity. First, he caused a continuous ribbon or strip of paper to move under a pencil by clock-work, that could be wound up. The paper moved horizontally. The pencil moved only up and down; when resting on the paper it made a mark—if for an instant only, a dot; if for a longer time, a line. When lifted from the paper it left a blank.... The grandeur of this wonderful alphabet of dots, lines, and spaces has not been fully appreciated....

"Not one of all the brilliant scientific men who have attached their names to the history of electro-magnetism had brought the means to produce the practical registering telegraph. Some of them had ascended the tower that looked out on the field of conquest. Some of them brought keener vision than others. Some of them stood higher than others; but the genius of invention had not recognized them. There was needed an inventor."

As soon as Morse left the ship Sully, and met his brothers Richard and Sidney, he told them that he had made an important invention, "one that would astonish the world, and of the success of which he was perfectly sanguine." He became an inmate of Richard's house, living there several months.

From this time onward for twelve years he labored to give his telegraph to mankind; labored in the midst of distressing poverty, the ridicule of acquaintances, and the indifference of the world. Three motherless children were dependent upon him, but he could do little for them.

On the corner of Nassau and Beekman Streets, in the newspaper building erected by his brothers,—they were the editors and proprietors of the "New York Observer,"—in the fifth story, a room was assigned to him which he used for studio, sleeping-room, kitchen, and workshop. On one side was his cot, on the other his tools and crude machine. He whittled the models, and then made the moulds and castings. Here, from day to day, the simplest food was brought him, he preparing his own tea.

In the year 1835, having been appointed professor of the Literature of the Arts of Design in the New York City University, he took rooms in the third story of the university building. "There," he says, "I immediately commenced, with very limited means, to experiment upon my invention. My first instrument was made up of an old picture or canvas frame fastened to a table; the wheels of an old wooden clock, moved by a weight to carry the paper forward; three wooden drums, upon one of which the paper was wound and passed over the other two; a wooden pendulum suspended to the top piece of the picture or stretching-frame, and vibrating across the paper as it passes over the centre wooden drum; a pencil at the lower end of the pendulum, in contact with the paper; an electro-magnet fastened to a shelf across the picture or stretching-frame, opposite to an armature made fast to the pendulum; a type rule, and type for breaking the circuit, resting on an endless band, composed of carpet-binding, which passed over two wooden rollers, moved by a wooden crank, and carried forward by points projecting from the bottom of the rule downward into the carpet-binding; a lever, with a small weight on the upper side; and a tooth, projecting downward at one end, operated on by the type; and a metallic fork, also projecting downward over two mercury-cups; and a short circuit of wire, embracing the helices of the electro-magnet connected with the positive and negative poles of the battery, and terminating in the mercury-cups."
