About Guglielmo Marconi
Guglielmo Giovanni Maria Marconi, 1st Marquess, 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 his 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 Wireless Telegraph & Signal Company (later the Marconi Company) in the United Kingdom in 1897. Marconi's experimental apparatus proved to be the first engineering-complete, commercially successful radio transmission system. 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. At the age of 18, Marconi returned to Bologna and became acquainted with Augusto Righi, a physics professor at the University of Bologna, who had done research on Heinrich Hertz's work.
