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".

All this that he did was based on work previously done by Tesla. after Marconi became world-famous for sending the first transatlantic message, Tesla responded this way: "Marconi is a good fellow. Let him continue. He is using seventeen of my patents."
