Irena Sendler, 1942
Sendler saved the lives of thousands of Jewish children during World War II, by smuggling them out of the Warsaw ghetto. She was a social worker and used sanitary inspections of the ghettos as a cover. Penalty at this time for harboring Jews was death - for one’s entire household. In 1943, Sendler was arrested by the Gestapo, severely tortured, and sentenced to death. The resistance saved her by bribing German guards on the way to her execution. Almost all of the parents of the children Sendler saved were killed at the Treblinka extermination camp.
