HARVARD LAW — In Nazi Germany, Géraldine Schwarz’s grandparents lived like many of their neighbors. They were not active participants in the genocidal war machine, but they didn’t oppose it, either. They took their place among the “Mitläufer” — those who follow the current. In doing so, they helped support the slaughter of millions of Jews and became Hitler’s accomplices, Schwarz says. The author of “Those Who Forget: My Family’s Story in Nazi Europe” spoke Tuesday at the Harvard Law School in an event co-sponsored by the Human Rights Program at Harvard Law School and HLS Advocates for Human Rights.
