Carl Zeiss was founded in Jena in 1846. Shortly thereafter, a large number of the company's products were sold abroad. Distribution was originally the responsibility of business associates and representatives. In 1893, the first representative outside Germany opened in London. The first production site outside Jena opened in Vienna in 1906. The two World Wars resulted in massive set backs to the company's internationalization endeavors. The representatives had to be refounded in practically all countries. Beginning around 1950, there were even two competing subsidiaries in many countries, from Carl Zeiss in Oberkochen, and from VEB Carl Zeiss Jena.
This situation was eliminated with reunification, but the fast-growing subsidiaries have been opening their own sales outlets in an increasing number of countries since the 1990s. Manufacturing subsidiaries outside Germany have become more and more important in the new millennium. Today, some product ranges are produced entirely outside Germany.
The history of Carl Zeiss in Ober- kochen began at the end of World War II when leading employees from Carl Zeiss Jena were taken to the West by American forces.
In 1846 Carl Zeiss opened an optical workshop in Jena where he built his first microscopes. It is still an important location for the company.
In 1857 Rudolf Winkel launched a mechanical company in Göttingen. In 1911 Carl Zeiss became the largest shareholder. Today Carl Zeiss develops and produces microscopes in Göttingen.
The optical company Engelbert & Hensoldt moved to Wetzlar in 1865. It was acquired by Carl Zeiss in 1928. Today Wetzlar is the home of Carl Zeiss Sport Optics.
