Julius Laack, later Julius Laack Soehne,[1] was a camera and lens maker, based at Curlandstrasse 60, Rathenow (Brandenburg, Germany).[2] The company seems to have started in 1884.[3] McKeown[4] lists a ferrotype camera from 1895, and a number of folding plate cameras. Laack lenses were used on smaller-format cameras at least up to the Second World War. During the time of the German Democratic Republic the company became state-owned and was part of VEB Rathenower Optische Werke (ROW), together with Emil Busch and Nitsche and Günther.[5]

Laack lenses, especially the Pololyt, appear on other German companies' cameras including the Altissa Altiflex and Altix, Welta Reflekta and KW Pilot Super. Laack also made a range of cine lenses as well as filters. In addition, Laack worked on other photographic implementations, such as film testers.[6]

Lenses

Laack was first and foremost an optical company making lenses for cameras, binocluars and microscopes. Laack produced a wide range of lenses for still photo and cine cameras as well as enlargers.[2][13] An advertisement in 1934 claimed that over 500,000 lenses had been produced by Laack and Laack Söhne.[3]
