Physicist and inventor — Guglielmo Marconi (Bologna 1874 – Rome 1937) was an Italian physicist and inventor, a pioneer of radio communications. A largely self-taught scholar and experimenter, he applied the electromagnetic waves predicted by Maxwell and produced by Hertz to the wireless transmission of signals over distance. He progressively refined antennas and circuits, managing to send telegraph signals over ever greater distances; in 1901 he achieved the first radio transmission across the Atlantic Ocean. His invention transformed maritime, military and civilian communications, laying the foundations of modern radio and telecommunications. In 1909 he received the Nobel Prize in Physics, shared with Karl Ferdinand Braun.
Trivia
Marconi radio equipment played a crucial role in rescuing the survivors of the Titanic in 1912, helping to save hundreds of lives.
Theories and contributions
- Wireless telegraphy — Transmission of signals over distance by means of electromagnetic waves, without cable connections.
- Transatlantic transmission (1901) — First radio link across the Atlantic, demonstrating the possibility of intercontinental communications.
