Georges Mendel was the inventor 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] it is likely that the company also made some view cameras for still photography. It was based in Paris, at 10bis, Boulevard Bonne-Nouvelle.
