Guglielmo Marconi, 1st Marquis of Marconi

Guglielmo Marconi, 1st Marquis of Marconi (April 25, 1874 – July 20, 1937) is an Italian inventor, and electrical engineer, known for his pioneering work on long-distance radio transmission, development of Marconi's law, and a radio telegraph system.

He is credited as the inventor of radio, and he shares the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".

Marconi is also an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in the United Kingdom in 1897 (which becomes the Marconi Company).

He succeeds in making an engineering and commercial success of radio by innovating and building on the work of previous experimenters and physicists.

In 1929, Marconi is ennobled as a Marchese (marquis) by King Victor Emmanuel III of Italy, and, in 1931, he sets up the Vatican Radio for Pope Pius XI.
