Once upon a time the Himmlers were just a normal German family, middle-class, hard-working, well-educated. There were three brothers, Gebhart, Heinrich, and Ernst. Heinrich grew up to become the head of Hitler’s SS, mastermind of the concentration camp system, and chief perpetrator of the Holocaust. When Katrin Himmler, Heinrich’s great-niece, was 15, one of her schoolmates asked during a history lesson if she was related to the Himmler. "Yes," she stammered, at which there was a deathly hush in the classroom and the teacher, embarrassed and unsure, quickly moved the lesson on. As she grew older, Katrin gave her family history a wide berth, but married to an Israeli whose family was confined to the Warsaw Ghetto and with a young, half-Jewish son, she realizes that she cannot evade the past so easily.
