Le Diocinescope Film Viewer, 1899 onwards

Huet & Daubresse, France. Extremely rare film viewer for 35 mm wide film material. First time the stepping mechanism, which puts strain on the film perforation, is not used for film transport, image fusion through continuous film transport is achieved by a rotating lens system around a Dove prism for use in daylight, works! (optical parts undamaged, but for continuous operation that is attractive to the public, the axis bearing needs mechanical improvement). Driven by hand crank, switchable for reverse transport. Spool size for 10 m film, focusable double-eyed viewing magnifiers (lens system must be cleaned inside), on the back: opening for inserting a ground glass screen, with adjustable reflex mirror. Black precious wood case with floral decoration (with small cracks due to age), height 36,5 cm. – Literature: "La Nature" from December 7, 1901, and George Sadoul, "History of Film" (1948). – Rightly awarded two gold medals at the 1900 World Exposition, it must have been a sensation to the public as a small, elegant device – here something works completely silently compared to the loud clattering projectors and there is no risk of fire from high-intensity lamps! According to our information, only two other devices are known. This film viewer with motion compensation is the optical-scientific ancestor of (most) slow motion film cameras and (most) film editing tables.
