Leopold Jessner (3 March 1878 – 13 December 1945) was a noted producer and director of German Expressionist theater and cinema.
A native of Königsberg, Jessner was a touring actor in his youth and turned to directing in 1911.
He was director of the Berlin State Theater from 1919 to 1925 and was known for bare stages in which flights of steps served as different spaces for scenes and directing actors to act in an oversimplified, unnatural manner.
These staircases would become regular fixtures in later German films, nicknamed "Jessnertreppe" in Jessner's honor, and would be used to full effect in the 1926 German Expressionist film Faust, directed by F.W.
As a Jew and a Socialist, he was forced to emigrate to the United States in 1933, after Adolf Hitler came to power in Germany.
