Synopsis Born in Bologna, Italy, in 1874, Guglielmo Marconi was a Nobel Prize-winning physicist and inventor credited with the groundbreaking work necessary for all future radio technology. Through his experiments in wireless telegraphy, Marconi developed the first effective system of radio communication. In 1899, he founded the Marconi Telegraph Company. In 1901, he successfully sent wireless signals across the Atlantic Ocean, disproving the dominant belief of the Earth’s curvature affecting transmission. Marconi shared with Karl Braun the 1909 Nobel Prize in Physics. He died in Rome in 1937.
