This is the question that historians have argued since the end of World War Two. How much did an average person know, and, more importantly, how responsible were they?  What made people “perpetrators,” “bystanders,” and “victims” within a wider context of coercion and consent? To explore this question is today’s guest, Richard Evans, author of “Hitler’s People: The Faces of the Third Reich.” We look at a connected series of biographical portraits of key Nazi figures that follows power as it radiated from Hitler to the inner and outer circles of the regime’s leadership. This includes personal lives of figures whose names appear in nearly all Nazi biographies, like Heinrich Himmler and Joseph Goebbels (“The Policeman” and “The Propagandist”), as well as professionals with skills deemed advantageous to the Nazi agenda, including Julius Streicher (“The Schoolmaster”) and the eugenicist Karl Brandt (“The Professional”), and some of the women in Hitler’s orbit such as Ilse Koch (“The Witch”) and Leni Riefenstahl (“The Star”). Through these biographies, one of our greatest historians explores the enduring and unnerving questions: How could human beings carry out such terrible and murderous atrocities? Were they degenerate, deranged psychopaths, or were they ordinary men doing their jobs? How can examining individual personalities help us reach an understanding of the evil and immorality that sustained the Nazi regime?
