Voigtlander & Sons
In 1756, Johann Christoph Voigtlander (1735-1797) founded the company in Vienna to produce spectacles, microscopes and telescopes. His three sons all worked for the business. After Johann-Christoph’s death, it was taken over by his youngest son, Johann Fredrick Voigtlander (1779-1859). In 1811, he built the first Galilean binocular telescope, which he patented in 1815. He went to improve and produce a range of lenses for different purposes. In cooperation with Professor Pretzval, in 1839 he produced the Petzval portrait lens and designed the Voigtlander all-metal camera to take advantage of the improved speed of the lens.
The company moved to Braunschweig in 1866. They continued to develop and market cameras through the late 19th and early 20th centuries. It is now part of Zeiss.
