Oskar Barnack (Nuthe-Urstromtal, Brandenburg, 1 November 1879 – Bad Nauheim, Hesse, 16 January 1936) was a German inventor and photographer who built, in 1913, what would later become the first commercially successful 35mm still-camera, subsequently called Ur-Leica at Ernst Leitz Optische Werke (the Leitz factory) in Wetzlar.[1]
