Rene Barthélemy (March 10th 1889 with Nangis - 1954 with Antibes) is an engineer French which was illustrated like pioneer in the development of the Télévision.
However, the invention of television cannot be allotted to only one man; it was a slow work of collective improvement between researchers and handymen of various countries of which the first concepts go back to the years 1880. They were the successive discoveries in electronic electricity and which made it possible to carry out the theoretical projects of the first researchers.
Shining qualified engineer of the University of Electricity (become Supélec), raises promotion 1909/1910, Rene Barthélemy becomes in 1929 chief of the new research laboratory on television, created by Jean the Duke at the request of Ernest Chamon, chairman of the Compagnie of the meters to Montrouge.
It is with a receiver using the disc of Paul Nipkow and mirror a mechanical camera of Weiler with 30 lines of definition, developped at the point in the buildings of the laboratory of the Company of the meters, which will be carried out on April 14th 1931 the first demonstration of television in France, at the University of electricity of Malakoff.
Continuing its work, it develops fine 1934 a new material in 60 lines of definition which will be used for the first French official emission of television. It takes place the April 26th 1935, under the aegis of Georges Mandel, Minister for postal and telecommunications authorities, since the studio of the street of Grenelle and consists of sequence a twenty minutes during which the actress Béatrice Bretty déclame a text reporting its recent round in Italy.
The December 2nd 1935, continuing the improvement of its apparatuses, it develops and carries out an emission in 180 lines of definition, but the time of “mechanical” television with disc is completed and from now on progress in electronics opens the way on television modern.
Television takes its rise, but the number of stations still remains very weak. Receiver “EMYVISOR” with cathode tube of Rene Barthélemy is marketed by EMYRADIO, about 1937. The official emissions are then thirty minutes per day.
Rene Barthelemy, from now on member of the Academy of Science, will continue, in spite of a precarious health, to work effectively in the field of television, while bringing there his inventive genius and his rigor.
