Helene Bertha Amalie "Leni" Riefenstahl (August 22, 1902 – September 8, 2003) was a German film irector, dancer and actress widely noted for her aesthetics and innovations as a filmmaker. Her most famous film was Triumph des Willens (Triumph of the Will), a propaganda film made at the 1934 Nuremberg congress of the Nazi Party. Riefenstahl's prominence in the Third Reich along with her personal friendships with Adolf Hitler and Joseph Goebbels thwarted her film career following Germany's defeat in World War II, after which she was arrested but never convicted of war crimes.
