Ernst Ludwig Kirchner

Ernst Ludwig Kirchner was a German Expressionist painter and printmaker. He was among the founders of Die Brücke, or "The Bridge", a group that helped lead the way to Expressionism in twentieth-century art. After a breakdown during the First World War he left army service. In 1937 the Nazis condemned his work as "degenerate", and over 600 pieces were sold or destroyed.
