Samuel Breese Morse, the painter, and Samuel B. Morse, the inventor, are the same person.
Morse had a celebrated career as a portraitist and sculptor and was an art professor at New York University.
In 1825 he helped found the National Academy of Design in New York City. About the same time, approaching 40, he began dabbling outside his field, experimenting with chemistry and electricity.
In 1836, he filed a preliminary patent on the telegraph and invented the Morse code, the dot-and-dash language that made all that clicking and buzzing make sense on the other end.
In 1843, the artist/inventor convinced the Congress to pony up $30,000 for a telegraph line between Washington, D.C., and Baltimore and on May 24, 1844, Morse sent the first long-distance message: “What hath God wrought!”
