Guglielmo Marconi

Guglielmo Giovanni Maria Marconi, 1st Marquess ( ; ; 25 April 1874 – 20 July 1937), was an Italian radio-frequency engineer, inventor, and politician known for his creation of a practical radio wave-based wireless telegraph system. This led to him being largely credited as the inventor of radio and sharing the 1909 Nobel Prize in Physics with Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy". His work laid the foundation for the development of radio, television, and all modern wireless communication systems.

As an entrepreneur and a businessman, Marconi founded the Marconi Company in the United Kingdom in 1897. In 1929, he was ennobled as a marquess () by Victor Emmanuel III. In 1931, he set up Vatican Radio for Pope Pius XI.
