Colour and Collaboration The Agfa story begins in 1867 in Rummelsburger See, on the outskirts of Berlin, when chemists Paul Mendelssohn Bartoldy and Carl Alexander von Martius founded the Gesellschaft Für Anilin-Fabrikation mbH.

Almost a century and a half of optical engineering: from taking lenses to sunglasses; from Rodenstock to Linos to Qioptiq to Excelitas. Rodenstock lenses and lens cells can be dated as follows: 50 000 1910 200 000 1920 400 000 1930 700 000 1935 900 000 1938 950 000 1940 2 000 000 1945 2 …
