Irena Sendler got permission to work in the Warsaw Ghetto as a plumber. She courageously smuggled babies in her tool box and carried larger children in her sack. She also trained her dog to bark when the Nazi soldiers were near, which muffled the sounds of the crying children. She helped save more than 2,500 children & was eventually caught & tortured. Sendler was nominated for the Nobel Peace Prize but was not selected. Al Gore won for his presentation on global warming...but she is a HERO!
