Innovative documentarian and notorious Nazi propagandist Leni Riefenstahl died Monday of undisclosed causes in Pöcking, Germany. The actress-turned-director chronicled the 1934 Nuremberg rally and 1936 Berlin Olympics in the influential Triumph of the Will (1935) and Olympia (1938), whose images still resonate powerfully. Her career in post-war ruins, Riefenstahl reinvented herself as a still photographer; a 1993 documentary, The Wonderful, Horrible Life of Leni Riefenstahl rekindled public interest in her exploits. She remained active and outspoken until her death, rationalizing her work for the Third Reich.
