Caption: Telegraph system. Historical artwork of operators using a Wheatstone telegraph system. The Wheatstone automatic telegraph consisted of a tape perforator, transmitter and receiver. A series of five wires (upper centre) allowed operators to enter a message using 20 different letters. Electric telegraphs were an important application of the newly-discovered electromagnetic force. Sir Charles Wheatstone patented the five-needle telegraph in 1837 with William Fothergill Cooke. This was the same year that Samuel Morse invented his telegraph in the USA. Published in La Telegraphie Historique (History of Telegraphy) by Alexis Belloc in 1888.
