Cassella AG, formerly Leopold Cassella & Co. and Cassella Farbwerke Mainkur AG, commonly known as Cassella, was a German chemical and pharmaceutical company with headquarters in Frankfurt am Main. Founded in 1798, in the Frankfurt Jewish Alley by Leopold Cassella, Cassella operated as an independent company until 1995, and was one of many predecessor companies of today's Sanofi. Its main products were dyes, drugs, cosmetics and various other chemical products. From 1949, Cassella focused increasingly on pharmaceuticals and cosmetics rather than its former primary focus, dyes. Much of its history is closely associated with the Gans family, a prominent family of industrialists and philanthropists and former owners of Cassella.
