Born at the end of the 19th century, Baumeister began his training in evening classes at the Kunstakademie in Stuttgart. From 1908, he attended Adolf Hölzel’s composition class, where he met Oskar Schlemmer. He developed his artistic expression by combining sand and putty in his artworks. He became professor of typography, commercial graphics and fabric printing at the Frankfurt School of Applied Arts. In 1930, he joined the Cercle et Carré group and, two years later, Abstraction-Création. With the rise of the Nazis, Baumeister became isolated and wrote The Unknown in Art. After the war, he became a professor at the Kunstakademie. He died in his studio with a paintbrush in his hand.
