Titre: Morse Apparatus and Alphabet, 1877
Légende: Voir la traduction automatique
Engraving entitled: Morse apparatus and alphabet. Print shows apparatus for sending and receiving coded telegraph messages, with the alphabet and numbers in Morse code. Samuel Finley Breese Morse (1791-1872) was an American contributor to the invention of a single-wire telegraph system based on European telegraphs, co-inventor of the Morse code, and an accomplished painter. In 1832, after having been helped by the American physicist J. Henry, he had the idea of a design for the electric telegraph. In 1844 the first telegraph line, about 65km long, was completed linking Washington to Baltimore. The first message sent by Morse was What hath God wrought; it was sent in a code of dots and dashes, the Morse code, which he had devised in 1838. There is an argument amongst historians that Morse may have received the idea of a plausible telegraph from Harrison Gray Dyar and he never acknowledged the help received by J. Henry.
