Groundbreaking Work and Nobel Prize
Marconi founded the Londonbased Marconi Telegraph Company in 1899. Though his original transmission traveled a mere mile and a half, on December 12, 1901, Marconi sent and received the first wireless message across the Atlantic Ocean, from Cornwall, England, to a military base in Newfoundland. His experiment was significant, as it disproved the dominant belief of the Earths curvature affecting transmission.Beginning in 1902, Marconi worked on experiments that stretched the distance that wireless communication could travel, until he was finally able to establish transatlantic service from Glace Bay in Nova Scotia, Canada, to Clifden, Ireland. For his work with wireless communication, Marconi shared the Nobel Prize in Physics with Karl Braun in 1909. Not long after, Marconis wireless system was used by the crew of the RMS Titanic to call for assistance.
Marconi held several positions in the Italian Army and Navy during World War I, starting the war as a lieutenant in 1914 and finishing as a naval commander. He was sent on diplomatic missions to the United States and France. After the war, Marconi began experimenting with basic short wave radio technology. On his beloved yacht, Elettra, he conducted experiments in the 1920s proving the efficacy of the beam system for longdistance communication. (The next step would lead to microwave transmission.) By 1926, Marconis beam system had been adopted by the British government as a design for international communication.In addition to his groundbreaking research in wireless communication, Marconi was instrumental in establishing the British Broadcasting Company, formed in 1922. He was also involved in the development of radar.
