As a boy, young Alfred Lessing was like most other children in his native Netherlands. He played with friends and loved his family. But there was one difference: he was Jewish. So when the Nazis overran his country in 1940, his mother sprang into action. Her one goal: save the family from extermination. In this three-part interview, Dutch immigrant Fred Lessing talks of love, hiding, and what we can learn from human atrocities. Interview: Part 1, Part 2, Part 3.
