From Hidden Child:
Approximately 1,200,000 Jewish children were deported and murdered by the Nazis and their collaborators in the Holocaust of World War II. Most of those who survived did so by being sent into hiding. Some were hidden with other Jews. Some went to convents and monasteries; others were hidden on farms or taken in by non–Jewish families and individuals. My name is Isaac Sztrymfman, and I was a hidden child.
