Optical Museum Jena. Life
In 1847 Carl Zeiss started making microscopes full-time. In 1861 he was awarded a gold medal at the Thuringian Industrial Exhibition for his designs.
Raised in Weimar Germany he became a notable lens-maker in the 1840s when he created high-quality lenses that were "wide open" or in other words had a very large aperture range that allowed for very bright images. At first his lenses were only used in the production of microscopes but when cameras were invented his company began manufacturing high-quality lenses for cameras.
