Oskar Schlemmer was one of the most versatile artists of the 20th century. He became famous for his stereometric figures in space that he represented without any individual attributes. Schlemmer was an important teacher at the Bauhaus; he created legendary stage settings and had a great influence on later generations of artists. When his 'Triadic Ballet' was first staged in 1922 in Stuttgart, Schlemmer attracted international attention. After Gropius' resignation in 1929, Schlemmer also left the Bauhaus and accepted a post at the Academy in Breslau. He was given a professorship at the 'Vereinigte Staatsschulen' in Berlin in 1932, but the National Socialists forced him to resign in 1933. During the War, Oskar Schlemmer worked at the 'Institut für Malstoffe' in Wuppertal together with Willi Baumeister and Georg Muche. In the postwar period, Schlemmer led a secluded life and made a series of small mystical 'Fensterbilder' (window paintings).
