Helene Bertha Amalie "Leni" Riefenstahl (22 August 1902 – 8 September 2003) was a German film director, actress and dancer widely noted for her aesthetics and innovations as a filmmaker. Her most famous film was Triumph des Willens (Triumph of the Will), made at the 1934 Nuremberg congress of the Nazi Party. Riefenstahl's prominence in the Third Reich along with her personal friendship with Adolf Hitler thwarted her film career following Germany's defeat in World War II, after which she was arrested but released without any charges.
