Marconi, Guglielmo

Guglielmo Marconi, the Italian engineer and inventor, visited Alexanderson in 1915 and bought one of his 50-foot alternators for the transatlantic Marconi Center in New Jersey. Within a few years, Alcxatidcrson s alternators were to be found in numerous countries. Using a 200-foot Alexanderson alternator, Marconi broadcast radio transmissions during World War I that were heard all over Europe.

By the time he arrived on borrowed funds at Cambridge in September 1895 to take up work at the Cavendish under its renowned director, J. J. Thomson, Rutherford had elaborated his observation into a device (ct detecting radio waves at a distance— in effect, the first crude radio receiver. Guglielmo Marconi was still laboring to perfect his version of a receiver at his father s estate in Italy for a few months the young New Zealander held the world record in detecting radio transmissions at a distance.

As the quantum theory of atomic structure came to be better understood and electricity better controlled, electronic theory became much more important. Spurred by the success of the electromagnetic telegraph of American inventor Samuel Morse (1791-1872), scientists sought other applications. The first major electronic application of worldwide importance was wireless radio, first demonstrated by Italian inventor Guglielmo Marconi (1874-1937). Radio depended on electronic devices known as vacuum tubes, in which structures capable of controlling... 

Radio pioneer Guglielmo Marconi initially transmitted radio signals over water. He was unable to transmit over land because prevailing laws in Europe gave government postal services a monopoly on message delivery.
