Schlemmer did not work as an architect. But since he created murals and installations in houses, we include him into this category.
In 1903 he began an apprenticeship as a draughtsman, was interested in cubism and the French avant-garde. At the beginning of World War I he was patriotic, but did not fight. In addition to painting, he was interested in theatre and that is why Walter Gropius asked him work at the Bauhaus. From 1921-1929 he taught and directed stone sculpture, mural painting and was involved in theatre and stage art. He also designed the Bauhaus signet in 1922. After Hannes Meyer became director of the Dessau Bauhaus, Schlemmer moved to the Breslau School of Arts and Crafts and taught a stage class.
When he heard about the closure of the Bauhaus in Dessau, he created the famous painting "Bauhaus Staircase" (Bauhaustreppe). As the Breslau school was closed, he moved to the Vereinigte Staatsschulen für freie und angewandte Kunst in Berlin, which, however, was closed by the Nazis in 1933. They also demoted Schlemmer, although he tried to make them understand his art in order to get commissions. He was unsuccessful, worked as a painter in Stuttgart and as a varnisher in Wuppertal and died of diabetes and jaundice.
