Guglielmo Marconi was an Italian inventor and businessman who developed practical radio communication. In 1901 his station sent the first radio signal across the Atlantic, and his wireless systems saved lives at sea. He shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun.

Biography

Early experiments

Marconi was born in Bologna to an Italian father and an Irish-Scottish mother. Inspired by Heinrich Hertz’s discovery of radio waves, he built transmitters at his family’s villa in 1895 and sent signals over increasing distances.

Britain and business

Finding little interest in Italy, he moved to England, patented his system in 1896 and founded the Wireless Telegraph & Signal Company, later the Marconi Company. He sent signals across the English Channel in 1899.

Across the Atlantic

On 12 December 1901 Marconi reported receiving the letter “S” in Morse code at St John’s, Newfoundland, sent from Poldhu in Cornwall. Ship-to-shore radio spread rapidly; Marconi operators on the Titanic in 1912 called for help, saving survivors.

Later life

He shared the 1909 Nobel Prize in Physics and continued work on shortwave and microwave radio. He became a senator and a supporter of Mussolini’s government. When he died in 1937, radio stations worldwide fell silent for two minutes.
