Morse telegraph receiver,19th century
Morse telegraph receiver. Historical illustration of the receiver of a telegraph machine used to communicate in Morse code. The messages arrived through wires as a series of long and short electrical pulses. Electromagnets attached to a printing head then converted these into dashes and dots. In Morse code,each letter and number is represented by a combination of dots and dashes. The code was printed on a stream of ticker tape,which was collected at far left. Morse sent the first telegraph message in 1844. Artwork from 'Electricite' (1911) by Max de Nansouty,part of the 'Les merveilles de la science' series of 1867-1891 by Louis Figuier
