In this Thursday, April 4, 2013 photo, Warsaw ghetto Holocaust survivor Aliza Vitis-Shomron's private mementos placed on a table at her living room in Kibbutz Givat Oz, Israel. Two days before her comrades embarked on an uprising that came to symbolize Jewish resistance against the Nazis in World War II, 14-year-old Aliza Mendel got her orders: Escape from the Warsaw Ghetto. The end was near. Nazi troops had encircled the ghetto, and the remaining Jewish rebels inside were prepared to die fighting. Her job, they told her, was to survive and tell the world about how the fighters died resisting the Nazis. In the 70 years since the revolt, she's been doing just that, publishing a memoir about life in the ghetto and lecturing about the uprising.
