"He who changes one person, changes the world entire." That is how Irena Sendler viewed life, and that view moved her to the heroic actions she displayed during World War II. As a Polish social worker who saw the disturbing treatment of the Jewish people by Hitler and the Nazis, Irena was determined to do all she could to provide help and safety for Jewish families. It was her bravery and leadership that led to the rescue of so many Jewish children from the Warsaw Ghetto.
