Hi, I'm Christina Hartman for About.com and today we're profiling the American inventor Samuel Morse -- the creator of the telegraph.Samuel Morse was born in Charlestown, Massachusetts, in April 1791. After attending the Phillips Academy, Morse went to Yale where he studied religious philosophy, mathematics, and the science of horses.Morse was an accomplished painter. In 1825, he was in Washington, D.C., working on a painting when he received a message from Connecticut that his wife was ill. By the time he made it home, his wife had already died and been buried. It was then Morse decided he wanted to leave painting and instead develop a form of rapid long-distance communication.In 1837, Morse was finally able to develop the electromagnetic telegraph, which transmitted messages through a single wire to another receiver. At that time, most telegraphs had required up to 26 wires — one for every alphabet. He developed a system where a combination of short and long signals represented letters and numbers. The system became known as Morse code. In 1840, Morse was awarded the patent for the single-wire telegraph.As Morse was developing his system, he was competing with William Cooke and Charles Wheatstone in Britain who were also developing an electrical telegraph. They patented their device in 1937 — three years before Morse. But Morse's system would win out because it's cheaper.In 1843, Congress appropriated $30,000 for a 38-mile telegraph system to be built between Washington and Baltimore. By 1851, it was the standard throughout Europe -- except for Britain, which kept the Cooke-Wheatstone model. Morse died in April of 1872 in New York — with an estate worth almost a half million dollars at the time.
