Abstract :
The roots of the future are in the past. This paper remembers the main events of the history of radio, events in which Guglielmo Marconi gave his fundamental contribution to the development of the new system of communication. This paper covers the period from the first transmission at Villa Griffone, near Bologna (Italy), in 1895, to the transmission across the Atlantic Ocean from Poldhu (Cornwall) to St. John´s (Newfoundland) in 1901
