Le premier message radiotélégraphique transatlantique

This marker is composed of two side-by-side plaques, one in English and the other in French.English
At Signal Hill on 12 December 1901, Guglielmo Marconi and his assistant, George Kemp, confirmed the reception of the first transatlantic radio signals. With a telephone receiver and a wire antenna kept aloft by a kite, they heard Morse Code for the letter "S" transmitted from Poldhu, Cornwall. Their experiment showed that radio signals extended far beyond the horizon, giving radio a new global dimension for communication in the twentieth century.



French

Le 12 décembre 1901, à Signal Hill, Guglielmo Marconi et George Kemp, son adjoint, captent le premier message radiotélégraphique d'outre-atlantique, munis d'un récepteur téléphonique et d'une antenne montée sur un cerf-volant, ils entendent le signal de la lettre S, en Morse, transmis à partie de Poldhe, comté de Cornwall. La preuve est ainsi acquise que les signaux radiotélégraphiques voyagent au-delà de l'horizon, conférant ainsi à la radio une dimension planétaire importante pour les communications au XXᵉ siècle.
