Franz Heckendorf

Franz Heckendorf (5 November 1888 – 17 August 1962) was a German expressionist painter closely associated with the Berlin Secession. He contributed works to the painting event in the art competition at the 1928 Summer Olympics. His work was highly regarded during the Weimar Republic but from 1937 was classed as ''entartete Kunst''. During World War II, he was incarcerated in various prisons and eventually in Mauthausen concentration camp for helping Jews escape over the Swiss border. Provided by Wikipedia
