Guglielmo (William) Marconi, like many inventors, did not discover the phenomenon that made his inventions possible. He used the discoveries of other men and turned their theoretical discoveries to practical use. Hertz discovewred that electric waves could be sent wirelessly, but the current was too weak to record what was sent. Branly invented a 'coherer' which amplified the current. Marconi put the two togwether and added a small device which reset the recorder each letter. This became electric batteries, induction coil to increase current, and a telegraph key to make and break the circuit.
