Georges Mendel (1863-1937) was the inventor and maker of several devices related to gramophones and cinema:
- A device to synchronize a cine presentation with sound from a gramophone. His first patent[1] was filed in 1906. A subsequent patent describes the application of (presumably) the same device to a gramophone and cinematograph.[2]
- An air valve, which was to release compressed air in response to the vibrations of a gramophone or phonograph record, and thus serve as a loudspeaker.[3]
- A cine projector with hand-cranked film transport and electric lamp (powered by a hand- or foot-driven magneto). The patent specifies that the lamp housing can be shifted up, down or sideways to recentre the projected image as desired during the projection.[4]
In some of the patents, Mendel described himself as a 'photographic apparatus manufacturer':[5] the company sold, and probably also made, some cameras for still photography.
Mendel opened his first business in 1889 at 4, rue de l'Échiquier, Paris; moved after a year to 22, boulevard Saint-Denis (a move of a couple of streets), and in 1900 moved to 10 & 10bis boulevard Bonne-Nouvelle (again, a short move along the street, presumably for better premises).[6] In the meantime he had bought the business of Enjalbert. He dealt in equipment by other makers as well as his own. He also sold cinema films made by Pathé, and later made many films, using his patented sound-synchronisation equipment.

- ↑ French Patent 370449, Régulateur distributeur automatique d'énergie électrique pour mobiles synchrones (Automatic distributor/regulator of electric power for synchronised drives). There are several related patents filed in other countries, and later French ones.
