Who was the inventor of the telegraph in this country?

Samuel F.B. Morse, who was born at Charlestown, Mass., April 27, 1791.
He began life as a painter, but did not give his whole attention to
art--chemistry and experiments in electricity and galvanism claiming
much of his time. He first conceived the idea of the telegraph in
1832, and exhibited his invention to Congress in 1837. He struggled on
with scanty means, and was about to give up in despair when Congress
appropriated $30,000 for an experimental line, which was opened on May
12, 1844, between Washington and Baltimore. Prof. Morse died in 1872,
but not before he had reaped honors and fortune from his invention.
