Note: Georges Demeny (1850 - 1917) was a chronophotographer, film maker, and an important pioneer of the early cinema. A physiology student of E.J. Marey, Demeny worked as an assistant at the Paris Station Physiologique where the first ever photo sequences of human and animal movement were shot, first on glass, and then on celluloid. The process, the earliest form of the motion picture, was known as Chronophotography. In 1892, four years before the Lumière brothers invented the Cinématographe, Georges Demeny patented the Phonoscope for showing moving images on glass or paper discs. He invented the revolutionary "beater movement" and reportedly also sketched a claw-mechanism which he showed to Louis Lumière in December 1894.
In 1895, Demeny formed a partnership with Leon Gaumont, a mechanic and film maker who had been employed in the Parisian workshops of Jules Carpentier. While Carpentier went on to construct the Lumière Cinématographe (and also possibly the cases of the Demeny cameras), Gaumont went into business on his own to exploit Demeny's beater principal, and became a major player in the French film industry. The name Gaumont lives on today.
Amongst the ten Demeny cameras that are believed to have survived, there are three principal models, with variations. Model A used unperforated film, Model B used perforated 60 mm. film, and Model C the new 35 mm. film. Of the three Demeny 35 mm. cameras to have been offered at auction in recent years, No. 260 was a small single-sprocket camera, while No. 1531 (Sotheby's London, September 2000) was a double-sprocket camera of apparently identical construction to the one here, but with the addition of a bicycle-chain driven from the crank to the rear film box for "taking up" the film. A leather belt connecting the upper sprocket and the top film box on No. 1512 serves the same purpose, and it is likely that a similar belt would originally have connected the crank to the lower film box. It is also possible that the single-sprocket cameras were intended for amateur, and the double-sprocket models for professional use by the earliest film-makers.
