Villa Griffone |
Early Experiments
During
1894 Marconi (aged 20) embarked on a study of the works of Heinrich Hertz
(1857-1894), who had died that year.
Marconi started his experiments on the application of Hertzian waves to
the transmission and reception of messages over a distance, without wires, in
late1894 at the Villa Griffone at Pontecchio Bologna, Italy, the family home.
He greatly improved on the performance of Hertz's apparatus. The
distance for transmission and reception of signals was progressively increased,
across a room, down the length of a corridor, from the house into the fields
until, in the early summer of 1895 and despite an intervening hill, he achieved
signal transmission and reception over a distance of about 2km. Success was
indicated initially by the waving of a handkerchief and progressed to the need
to fire a gun.
