1901 – Guglielmo Marconi receives the first transatlantic radio signal
Guglielmo Giovanni Maria Marconi, 25 April 1874 – 20 July 1937, was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission, development of Marconi’s law, and a radio telegraph system.
He is credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun “in recognition of their contributions to the development of wireless telegraphy”
On 12th December 1901, using a 500-foot (150 m) kite-supported antenna for reception and signals transmitted, Guglielmo Marconi receives the first transatlantic radio signal, the letter “S” [***] in Morse Code).
The distance between the two points was about 2,200 miles (3,500 km).
Extra Note: Over the years, the Marconi companies gained a reputation for being technically conservative, in particular by continuing to use inefficient spark-transmitter technology, which could be used only for radio-telegraph operations, long after it was apparent that the future of radio communication lay with continuous-wave transmissions which were more efficient and could be used for audio transmissions.
