Needle Telegraph
Personaje: COOKE, William Fothergill.
Personaje: WHEATSTONE, Charles.
The growth of the railways from 1825 onwards brought with it a need for a new form of communications that could work over large distances and in any weather. Charles Wheatstone and William Cooke were two Englishmen who on 25th July 1837 demonstrated a system for sending messages using electricity. A set of magnetic needles could be deflected by an electric current such that the needles would point to a particular letter on a grid. This demonstration shows how a 4 needle telegraph - a slightly later model of the July 1837 original - operates and how letters could be communicated. The needle telegraph started a telecommunications revolution based on electrical communication.
