Edouard Branly , born with Amiens the October 23rd 1844 and died in Paris the March 24th 1940, is a physicist French pioneer of the radio.

The man and his work

Without work of Branly, Guglielmo Marconi could not have carried out in 1895 the radiotelegraphic connections which made it famous. The breadboard construction of Hertz had a range of a few meters. Supplemented by the detector of electromagnetic waves of Branly and the antenna of Popov, of tens, then hundreds of kilometers could be covered. Branly was also an experimenter in the field of the Télécommande by radio, prototype of the Radiocommande universally used nowadays to operate as well a television set as on a space probe.

Branly is the type of the Savant French worker, impassioned and obstinate of this time. Catholic convinced, it had as well to fight to obtain means on behalf of the direction of the catholic Institut of Paris, as against the anticlericals at that time agitated by the Separation of the Church and the State.

Part of the material of sound Laboratoire is exposed to the Branly museum, in the enclosure of the catholic Institute, 21 Rue of Assas, in the {{VIe}} district of Paris. In this building now occupied by the Institute of higher learning of electronics of Paris, one can visit three parts of his laboratory, of which its office and a room transformed into splendid Faraday screen room by plates of Cuivre affixed on the six faces.
