"Leopold Jessner (3 March 1878\u201313 December 1945) was a noted producer and director of German Expressionist theater and cinema. His first film, Hintertreppe (1921), is considered a major turning point which paved the way for the later German Expressionist experiments of German filmmakers F.W. Murnau, Fritz Lang, and G.W. Pabst. A native of K\u00F6nigsberg, Jessner was a touring actor in his youth and turned to directing in 1911."@en . "1878Z"^^ . "Jessner, Leopold"@en . "German film producer" . "1945Z"^^ .
