Oskar Barnack 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 in Wetzlar. From Wikipedia
Delivered to inventor Oskar Barnack in 1923, the prototype far surpassed its €2 million estimate when it opened at €800,000 in a Wetzlar auction.
