jan 1, 1809 - Samuel Soemmering Invents The Electric Telegraph

Description:

Samuel used 35 wires with gold electrodes in water to send a message. A telegraph message is sent and received by an operator and then delivered in written form as a telegram. They were used historically to record information quickly, signalled emergencies and to notify families of serious death or injury during war.
