Willi Baumeister (January 22, 1889 - August 31, 1955) was a German painter, scenic designer, and typographer.
Baumeister was born in Stuttgart. There, he was educated as a decoration painter between 1905 and 1907. At the same time, he began to study art at the Stuttgart Art Academy (Kunstakademie) under Robert Poetzelberger, Josef Kerschensteiner, and Adolf Hölzel, but had to interrupt this because of obligatory military service.
In 1926, Baumeister married the painter Margarete Oehm. In 1927, he started teaching as professor at the Städelschule (Municipal School for Art) in Frankfurt am Main, but was removed from this position on March 31, 1933, by the Nazis.
Baumeister died in Stuttgart.
