Guglielmo Marconi
Guglielmo Marconi (25 April 1874 – 20 July 1937) was an Italian inventor and electrical engineer. He was a pioneer of long-distance radio transmission.[1] which he used to build up a radio telegraph system. Marconi is often named as the inventor of radio. He shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun.[2][3][4]

Much of Marconi's work in radio transmission was built on previous experimentation,[5] and work by others. When he was twenty years old, based on the experiments of Hertz, Popov, Lodge, Bose, and Tesla, Marconi began his own experiments.
As an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in Britain in 1897, Marconi became wealthy in the business of radio, mainly for ships at sea.[6][7] In 1924, he was ennobled as Marchese Marconi. Back in Italy, he went on to become a member of the Grand Council of Fascism.

Marconi's first transmitter incorporating a monopole antenna. It consisted of an elevated copper sheet (top) connected to a Righi spark gap (left) powered by an induction coil (centre) with a telegraph key (right) to switch it on and off to spell out text messages in Morse code.
British Post Office engineers inspect Marconi's radio equipment during a demonstration on Flat Holm Island, 13 May 1897. The transmitter is at the centre, the coherer receiver below it, and the pole supporting the wire antenna is visible at top.
Plaque on the outside of the BT Centre commemorates Marconi's first public transmission of wireless signals.
