Until WWI many great companies cooperated with Goerz. This company continued to operate independently in the US until 1972. In 1895 Goerz founded a branch in New York that started own production in 1902 and was to become the C. A telescope for viewing a total eclipse and a 3-color-projector was made for the famous Dr. Another big success was the making of scientific telescopes. In 1903 it founded a department for military optics which became the world's largest military optics maker. Other products of Goerz were meteorological and aeronautical instruments, binoculars and Alethar repro lenses, gun scopes and another camera shutter, the Sector shutter. The first one was the Goerz-Anschütz Moment-Apparat of 1890, a box camera for 9x12cm plates with a good lens mounted on the front plate. These were mainly, but not exclusively, strut folding cameras, known as Ottomar Anschütz or Goerz Anschütz cameras, and many branded Ango as word derivation for Anschütz and Goerz. A specialty of Goerz were the cameras with "rouleau-shutter" since the company had the exclusive right to produce the fast focal plane shutter (1/1000sec.) that Ottomar Anschütz (1846-1907) had invented in 1883. Goerz is known primarily for Anschütz cameras, for Doppel-Anastigmat, Hypergon, Artar, Pantar, Tenaxiar, Tenastigmat, Hypar, Hycon, Certar, Gotar, Frontar, Dialyt, Syntor, Celor, Kalostigmat, Paraplanat, Choroskop, Lynkeioskop, Dogmar and the legendary Dagor camera lenses, and for Tengor and Tenax cameras, later continued by Zeiss Ikon. In 1888 Goerz employed the engineer Carl Moser (1858-1892) and the optician Karl Hertel to start the development of lenses. Hintze's workshop in 1888 his company became a camera maker itself, named Optische Anstalt C. Originally Goerz sold mathematical tools for schools, since 1887 also cameras. Goerz was founded in 1886 by Carl Paul Goerz (1854-1923), a salesman who once had been in apprenticeship at Emil Busch in Rathenow and later was partner of Eugen Krauss in Paris.
