Morse, Samuel Finley Breese
Morse's interest in electricity, aroused in his college days, was further stimulated by the lectures of James F. Dana in 1827 and later by contacts with university faculty. Learning in 1832 of Ampère 's idea for the electric telegraph, Morse worked for the next 12 years, with the aid of the chemist Leonard Gale, physicist Joseph Henry , and machinist Alfred Vail to perfect his own version of the instrument. So many phases of the telegraph, however, had already been anticipated by other inventors, especially in Great Britain, Germany, and France, that Morse's originality as the inventor of telegraphy has been questioned; even the Morse code did not differ greatly from earlier codes, including the semaphore. In any case, in 1844 Morse demonstrated to Congress the practicability of his instrument by transmitting the famous message
What hath God wrought over a wire from Washington to Baltimore. Morse subsequently was compelled to defend his invention in court, although by then he commanded the acclaim of the world. He later experimented with submarine cable telegraphy. Both Morse and John Draper were instrumental in introducing the daguerreotype in the United States.
