On this original linen-backed lithograph from 1932 (includes original specification sheet), Actiengesellschaft C. P. Goerz Optische Ansalt (The CP Goerz Optical Institution), Patented improvements in sighting telescopes for use with anti-aircraft guns. The CP Goerz Optical Institution was a company founded by Carl Paul Goerz. Originally, it made geometrical drawing instruments for schools. From 1888 it made cameras and lenses. During the First World War, Goerz's main production was for the German and Austrian military. Goerz is known primarily for Anschütz strut-folding cameras, Dagor lenses and Tengor, Tenax cameras, (later continued by Zeiss Ikon) and Minicord subminiature camera. C. P. Goerz also made a series of telescopic sights for sporting rifles that saw some use during the shortage of military sniping rifles experienced during the early stages of the trench warfare that was to characterize much of World War I.
In 1895 Goerz founded a branch in New York that was to become the C. P. Goerz American Optical Co in 1905. This company continued to operate independently in the US until 1972.
