Guglielmo Marconi (Italian: [ɡuʎˈʎɛːlmo maɾˈkoːni]; 25 April 1874 – 20 July 1937) was an Italian inventor, known for his pioneering work on long distance radio transmission and for his development of Marconi's law and a radio telegraph system. Marconi is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".

In 1924, he was ennobled as a Marchese.
