Feininger started to work as a fine artist at the age of 36. He was a member of the "Berliner Sezession" in 1909. He was associated with expressionist group Die Brücke, the Novembergruppe, Gruppe 1919, the Blaue Reiter circle and The Blue Four. When Walter Gropius founded the Bauhaus in Germany in 1919, Feininger became the master artist in charge of the printmaking workshop. He designed the cover for the Bauhaus 1919 manifesto: an expressionist woodcut 'cathedral'. He taught at the Bauhaus for several years. Among the students who attended his workshops were Ludwig Hirschfeld Mack (German/Australian, 1893–1965), Hans Friedrich Grohs (German 1892 - 1981) and Margarete Koehler-Bittkow (German/American, 1898–1964)
