Georges Demenÿ

Georges Emile Joseph Demeny ( born June 12, 1850 in Douai, † December 26, 1917 in Paris) was a French film technology pioneer.

Demeny was a research assistant at the taxidermist and physiologist Etienne Jules Marey, in which capacity he built the Photo Chronographe Chrono or Photographe. With the " Chrono. Demeny " has become known a very simple but effective film drive, called the Bat ( Batteur; beater, Dog Movement).

Demeny is the French spelling of the Hungarian name Demenÿ. Georges Demeny strove for communication with the deaf. An apparatus built by him shows himself as moving images in close-up, clearly articulating " Vive la France " or " Je vous aime ". People with hearing impairment should thus can learn to lip-read more easily. At the Exposition Internationale de Photographie from 1892 to Paris, he exhibited his " Photo Phone " from that contained 24 phase images. You could also phone with the photo project, but only to a limited extent, because the image plate turned continuously as the Dickson'schen Kinetoscope very short light times were appropriate.

Demeny felt unappreciated rightly by Professor Marey. He founded in 1894 a trading company for the use of his invention, which was protected by the French patent, No. 233'337, 10 October 1893 German Reich Patent No. 80'424 of 12 December 1893. He used 60 millimeter wide film and did not leave until 1897, for 35 - mm film, Léon Gaumont after the Chrono. , Système Demeny published in late 1896.

Déménys original recording apparatus has been preserved. In addition, a replica was recreated.
