Guglielmo Marconi, Italian radio pioneer, c 1902
Guglielmo Marconi (1874-1937) discovered a way in which waves could be used to send messages from one place to another without wires or cables. Having read about Hertz's work with electromagnetic waves, he began to carry out his own experiments and in 1894 he successfully sounded a buzzer 9 metres away from where he stood. Marconi shared the 1909 Nobel prize for physics with Karl Ferdinand Braun (1850-1818). The picture shows Marconi and his technical system that included a spark-producing radio transmitter, a coherer receiver, a telegraph key, and a telegraph register to record messages received in Morse code.
