Umbo (Otto Umbehr; 1902-80), German photographer. Although he had intended to study painting in Düsseldorf, in 1921 Umbo instead became Johannes Itten's student at the Bauhaus. He later cited this contact as a key influence on his development as a photographer. In 1924, he moved to Berlin, where he opened a studio and joined the capital's dynamic arts scene. He also became involved with film, working with Walter Ruttmann on Berlin, Symphony of a Great City (1927). Dephot, the Berlin picture agency, employed Umbo until its closure in 1932. During the Second World War, his studio and archive were destroyed. Only in the 1970s was his early work rediscovered, leading to a reassessment of his role in the German avant-grade. The photograms, photomontages, and surreal images from Berlin's 1920s theatre district are in stark contrast to his later photojournalism. In 1948, Umbo returned to professional photography, teaching at the Werkkunstschule, Hanover, until 1974.
