Guglielmo Giovanni Maria Marconi [11] [12] was born in Palazzo Marescalchi in Bologna on 25 April 1874, the second son of Giuseppe Marconi (an Italian aristocratic landowner from Porretta Terme who lived in the countryside of Pontecchio) and his Irish wife Annie Jameson (daughter of Andrew Jameson of Daphne Castle in County Wexford, sister of Scottish naturalist James Sligo Jameson, and ...
These developments allowed Guglielmo Marconi to turn radio waves into a wireless communication system. The idea that the wires needed for electrical telegraph could be eliminated, creating a wireless telegraph, had been around for a while before the establishment of radio-based communication.
In 1894, the young Italian inventor Guglielmo Marconi began working on the idea of building long-distance a wireless transmission systems based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. [22]
Over several years starting in 1894, the Italian inventor Guglielmo Marconi worked on adapting the newly discovered phenomenon of radio waves to communication, turning what was essentially a laboratory experiment up to that point into a useful communication system, [27] [28] building the first radiotelegraphy system using them.

Although development of the first radio wave communication system is attributed to Guglielmo Marconi, his was just the practical application of 80 years of scientific advancement in the field including the predictions of Michael Faraday, the theoretical work of James Clerk Maxwell, and the experimental demonstrations of Heinrich Rudolf Hertz.

Marconi National Historic Site, located at Table Head in Glace Bay, is the site of Guglielmo Marconi's first transatlantic wireless station, callsign VAS, and the first wireless message sent from North America to Europe on December 15, 1902.

Italian inventor Guglielmo Marconi begins developing the first radio wave based wireless telegraphy communication system [6] [7] 1895: Indian physicist Jagadish Chandra Bose conducts experiments in extremely high frequency millimetre waves using a semiconductor junction to detect radio waves [8] [9] 1895
By 1926 Marconi would be able to use shortwave radio to link the British Empire, making the former long-wave transatlantic service and its Louisbourg receiving station obsolete. The Marconi Towers transmitter site on Cape Breton was upgraded to broadcast voice and operated until 1945; the Louisbourg station closed in 1926.
