During WWII, Irena was given permission to work in the Warsaw Ghetto, as a plumbing/sewer specialist. She had an ulterior motive.
Being German, Irena knew what the Nazi plan was for Jews.
Irena smuggled out infants in the bottom of a tool box she carried in the back of her truck. She used a burlap sack for bigger children.
She also had a dog in the back that she trained to bark when Nazi soldiers let her in and out of the ghetto. The soldiers wanted nothing to do with her dog. The barking covered noises of the infants and children.
Irena managed to smuggle out and save 2500 infants and children, before she was caught. The Nazis broke both her legs and arms, and beat her severely.
Irena kept a record in a jar buried under a tree in her back yard of all the children she smuggled out.
After the war, she tried to locate all parents that may have survived to reunite families, but most had been gassed.
The children she could not reunite were placed with foster families or adopted.
Irena was nominated for the 2008 Nobel Peace Prize. She was not selected.
Al Gore won for a slide show on Global Warming.
