Zeiss, << tsys or zys, >> Carl (1816-1888), was a German maker of optical instruments. He opened a small workshop for making scientific instruments in Jena, Germany, in 1846. Twenty years later, Ernst Abbe, a teacher in Jena working in the Zeiss shop, developed a greatly improved optical glass. Abbe, an excellent scientist, and Zeiss, an able businessman, developed the Zeiss works into the world’s leading manufacturer of optical goods. Zeiss was born in Weimar, Germany.
