More about Carl Zeiss:
Carl Zeiss, branded as ZEISS, is a German manufacturer of optical systems, industrial measurements and medical devices, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) they built a base for modern optics and manufacturing. There are currently two parts of the company, Carl Zeiss AG located in Oberkochen with important subsidiaries in Aalen, Göttingen and Munich, and Carl Zeiss GmbH located in Jena.
Carl Zeiss opened an optics workshop in Jena in 1846. By 1847 he was making microscopes full-time. By 1861 Zeiss was considered to be among the best scientific instrument makers in Germany with about 20 people working under him with his business still growing. By 1866 the Zeiss workshop sold their 1,000th microscope. In 1872 physicist Ernst Abbe joined Zeiss and along with Otto Schott designed greatly improved lenses for the optical instruments they were producing. After Carl Zeiss's death in 1888, the business was incorporated as the Carl-Zeiss-Stiftung in 1889.
By World War I, Zeiss was the world's largest location of camera production. Zeiss Ikon represented a significant part of the production along with dozens of other brands and factories, and also had major works at Dresden.
Currently ZEISS employs over 24,946 workers over four sites in Germany, China, India and USA. The company is always developing and in 2014/2015 turnover figures were near to 4.51 Billion Euro.
