4 Barnack, Oskar
SUBJECT AREA: Photography, film and optics[br]b. 1879 Berlin, Germanyd. January 1936 Wetzlar, Germany[br]German camera designer who conceived the first Leica camera and many subsequent models.[br]Oskar Barnack was an optical engineer, introspective and in poor health, when in 1910 he was invited through the good offices of his friend the mechanical engineer Emil Mechau, who worked for Ernst Leitz, to join the company at Wetzlar to work on research into microscope design. He was engaged after a week's trial, and on 2 January 1911 he was put in charge of microscope research. He was an enthusiastic photographer, but excursions with his large and heavy plate camera equipment taxed his strength. In 1912, Mechau was working on a revolutionary film projector design and needed film to test it. Barnack suggested that it was not necessary to buy an expensive commercial machine— why not make one? Leitz agreed, and Barnack constructed a 35 mm movie camera, which he used to cover events in and around Wetzlar.The exposure problems he encountered with the variable sensitivity of the cine film led him to consider the design of a still camera in which short lengths of film could be tested before shooting—a kind of exposure-meter camera. Dissatisfied with the poor picture quality of his first model, which took the standard cine frame of 18×24 mm, he built a new model in which the frame size was doubled to 36×24 mm. It used a simple focal-plane shutter adjustable to 1/500 of a second, and a Zeiss Milar lens of 42 mm focal length. This is what is now known as the UR-Leica. Using his new camera, 1/250 of the weight of his plate equipment, Barnack made many photographs around Wetzlar, giving postcard-sized prints of good quality.Ernst Leitz Junior was lent the camera for his trip in June 1914 to America, where he was urged to put it into production. Visiting George Eastman in Rochester, Leitz passed on Barnack's requests for film of finer grain and better quality. The First World War put an end to the chances of developing the design at that time. As Germany emerged from the postwar chaos, Leitz Junior, then in charge of the firm, took Barnack off microscope work to design prototypes for a commercial model. Leitz's Chief Optician, Max Berek, designed a new lens, the f3.5 Elmax, for the new camera. They settled on the name Leica, and the first production models went on show at the Leipzig Spring Fair in 1925. By the end of the year, 1,000 cameras had been shipped, despite costing about two months' good wages.The Leica camera established 35 mm still photography as a practical proposition, and film manufacturers began to create the special fine-grain films that Barnack had longed for. He continued to improve the design, and a succession of new Leica models appeared with new features, such as interchangeable lenses, coupled range-finders, 250 exposures. By the time of his sudden death in 1936, Barnack's life's work had forever transformed the nature of photography.[br]Further ReadingJ.Borgé and G.Borgé, 1977, Prestige de la, photographie.BC
