 Morse became convinced that he could somehow send a message along a wire by opening and closing an electrical circuit, which could be recorded by an electromagnet on a piece of paper via a written code.
Back in the U.S., he moved forward with his idea, meeting with Joseph Henry, another scientist working in electromagnetism—and the man who would later become the first secretary of the Smithsonian Institution, in 1846. “He met with Henry, who explained how the electromagnets worked and showed his experimental ones,” says Wallace. “And if you look at the electromagnets—the ones Morse uses, and the experimental ones from Henry—it’s obvious they’re the same design. He’s definitely riffing off of Henry, as far as the electromagnet, which is one of the most important pieces of the apparatus.”
Morse returned to his New York apartment and, in 1837, he crafted a primitive telegraph receiver—now part of the Smithsonian’s collections and currently on display at the American Art Museum—that was able to register and record the fluctuations in an electrical circuit. “The most interesting thing about the prototype is that he took an artist’s canvas stretcher and made it into a telegraph receiver,” Wallace says. “So right there, you can see the shift from painter to telegrapher, all in one piece.”
With a means of recording electromagnetic signals theoretically in place, Morse worked with Gale, Vail and others over the next several years to improve the system and make it practical for use over far distances, incorporating Vail’s transmitter key and a code of dots and dashes, which of course would become known as Morse Code. Despite these improvements, the group had some difficulty convincing others that telegraphy was a worthy investment. “It was not difficult to convince people at the time that it was potentially useful,” Wallace says. “What really was the hard sell that Morse and others had to make was whether it could be practical. Could you create wires miles and miles long and send a signal through them?”
