Meet the Hero: Irena Sendler. âIf you see someone drowning, you must jump in to save them, whether you can swim or not.â Irena Sendler was just 7 years old when her father spoke those words. A doctor, he had contracted typhus while caring for poor Jewish people afflicted by the epidemic in their small Polish town. Irenaâs father died shortly thereafter, but like him, she would devote her life to saving othersâincluding more than 2,500 Jewish children during WWII. Irena was born in 1910 and grew up an only child in the Polish town of Otwock.
