I stumbled upon a documentary called 'The number on great-grandpa's arm' told from the perspective of a Holocaust survivor and his great-grandson. It even included a few rare color photographs of the Jewish ghetto. It's fascinating. He was sent to several camps until he wound up in Auschwitz.
I watched a series on PBS called the Story of the Jews. It was a fascinating series. The Story of the Jews with Simon Schama | PBS
