1920-1927
Paul Franke and Reinhold Heidecke founded Franke & Heidecke in Braunschweig on 1 February 1920. The firm first concentrated on stereo cameras, beginning with the plate-based Heidoscop. The roll-film Rolleidoscop of 1926 provided the first documented use of the Rollei name, conventionally explained from roll film and Heidecke, and supplied the mechanical and optical starting point for a compact twin-lens camera.
