Carl Bamberg (1847-1892) served an apprenticeship with Carl Zeiss at Jena and studied at the Universities of Jena and Berlin before establishing a "Werkstätten
für Präzisions-Mechanik und Optik" in Friedenau, a suburb of Berlin, in 1871. After Bamberg's death, the firm was managed by his widow, and then by his son. Bamberg merged with the Centralwerkstatte Dessau in 1921, forming a new company known as Askania Werke.
