Karl Peter Röhl was both a student and teacher at the Bauhaus. Röhl studied at the Staatliches Bauhaus Weimar, where he also had a studio, from April 1919 to spring 1921. He was a friend of Walter Dexel and Theo van Doesburg. In 1922, van Doesburg taught his de Stijl class in Röhl’s studio.
Röhl was the director of the preparatory classes at the Städelschule in Frankfurt am Main from 1926 to 1942. Shortly after, he was sent to the front and was captured and became a prisoner of war. After returning to Germany in 1946, he worked as a freelance artist until his death in 1975.
