Telegraph transmitter and receiver. This apparatus was designed by the French inventor Auguste Jean-Baptiste Tauleigne (1870-1926). At right is the relay where the message is tapped out. Headphones are at centre. At left is the recording part of the apparatus. Morse code was developed from 1836 as a means of encoding messages for transmission using telegraphy. The dots and dashes could be printed onto a strip of paper, as seen here. Photograph published in 'La Telegraphie Sans Fil' (Wireless Telegraphy, 1914), by the French geophysicist Alphonse Berget (1860-1934).
