Guglielmo Marconi

Born: Bologna, Italy, 25 April 1874

Died: Rome, 20 July 1937

As a student, Guglielmo Marconi was particularly interested in magnetism and the application of Hertzian waves. On 2 June 1896 he applied for his first patent concerning radio. A highly practical and enterprising man, Marconi was quick to commercialize his discoveries and, in July 1897 he founded in London the first company for wireless telegraphy. In 1899 he managed to transmit by radio a message across the English Channel and, in 1901, he sent signals across the Atlantic Ocean from Cornwall, England to Signal Hill, Newfoundland. By 1907 a transatlantic wireless service had been established and in 1909 he was awarded the Nobel Prize for physics. In 1924 he discovered skywave transmission which enabled him to offer a world-wide communication service. Throughout his life, Marconi dedicated himself to the expansion of wireless telegraphy and a total of nearly 800 patents were awarded either to him or the companies he directed.

Aleksander Popov

Born: Urals, USSR, 16 March 1859

Died: St. Petersburg, USSR, 13 January 1906

Aleksander Stepanovich Popov was a lecturer in physics at the Russian Imperial Navy's school at Kronstadt near St. Petersburg. After Hertz had demonstrated the existence of electromagnetic waves Popov experimented with ways of detecting them by a receiver. His experiments were demonstrated on 7 May 1895 to the Russian Physics and Chemistry Society and reported a few days later in the Kronstadtskii Vestnik. The report concluded that the aim "is to show that it is theoretically possible to transmit signals over a certain distance without the use of conductors, in other words, after the fashion of visual telegraphy but with the aid of electrical radiations".
