He was founder and president of Zoomar, INC, and later took over Kilfiitt. Along with many other inventions, the Voigtländer Zoomar 2.8/36-82mm is considered his most important). The camera is probably the first 360° panorama camera for 35mm film that was built and patented. The body is in a case mounted on a rotating disc. Exposure was via a mirror which was mounted in front of the lens. A museum piece! Including: a copy of the patent and other camera descriptions and information, accessories
