In 2009, Dr. Wendy Lower, the acclaimed author of Hitler’s Furies and chair of the United States Holocaust Memorial Museum’s Academic Council, was shown a photograph just brought to the Museum. The image—a rare “action shot” documenting the horrific final moment of a family’s murder—drove her to conduct years of forensic and archival detective work in Ukraine, Germany, Slovakia, Israel, and the United States, recovering new layers of detail about the Nazis’ open-air massacres in eastern Europe and the role of the family unit in Nazi ideology. In her new book The Ravine: A Family, a Photograph, a Holocaust Massacre Revealed, Lower explores the exceptional image and the new understandings it has unlocked about the Holocaust. Join Lower for a discussion about the book and her research with Paul Salmons, a Holocaust education specialist, curator of Auschwitz. Not long ago. Not far away, chief curator of Seeing Auschwitz, and consultant to the United States Holocaust Memorial Museum.
