Morse, Samuel Finley Breese (1791–1872)
American inventor of an electric telegraph. His first crude model was designed
in 1832, and by 1835 he could demonstrate a working model. With considerable
help from Joseph Henry (which later
he refused to acknowledge) he developed by 1837 electromagnetic relays to
extend the range and capabilities of his system. Charles Wheatstone's
invention had preceded Morse's, so that he was unable to obtain an English
patent, and in the US official support did not come until 1843. His famous
message, "What hath God wrought!", was the first sent on his Washington-Baltimore
line on May 24, 1844. For this he used Morse
code, devised in 1838. In early life, Morse was a portrait painter.
