Georges Emile Joseph Demenÿ (also Démény , born June 12, 1850 in Douai ; † October 26, 1917 in Paris ) was a French film technology pioneer.

Demenÿ was a scientific assistant and taxidermist at the physiologist Etienne Jules Marey , in which capacity he built the photochronograph and chronophotograph . With the "Chrono" a very simple but effective film drive has become known, the so-called Schläger ( French : batteur ; English : beater , dog movement ).

Georges Demenÿ tried to communicate with the deaf. An apparatus he built shows himself in close-up as moving images , clearly articulating “Vive la France” or “Je vous aime”. It should make it easier for people with hearing impairments to learn to read by lips. At the Exposition Internationale de Photographie in Paris in 1892, he exhibited his Photophone , which contained 24 phase images. You could also project with the photophone , but only to a limited extent because the image plate rotated continuously and, as with Dickson's kinetoscope, only very short bright times were useful.

Demenÿ did not feel appreciated by Professor Marey. In 1894 he founded a company to exploit his invention, which was protected by French patent no. 233337 of October 10, 1893 and German imperial patent no. 80424 of December 12, 1893. The Chronophotograph, Système Démény was brought onto the market by Gaumont at the end of 1896 . He initially used 60 millimeter wide film (which made coloring easier) and only switched to 35 mm film in 1897 .

Demenÿ's original recording apparatus has been preserved. A replica was also made.
