Irena Sendler, born on February 15, 1910, would grow up to be one of the most incredible heroes of WWII. Irena’s father was a doctor, and when he passed away when she was just seven years old, she decided to study medicine in his honor. Ever since she made this decision, Irena’s life became more and more geared towards helping everybody around her, rather than worrying about herself. Irena finally became a registered nurse and was promptly shipped away to the Warsaw Ghetto, where she was forced to see the atrocities Nazi party members carried out on their captives. Upon seeing these conditions, Irena realized it was finally her time to make a big difference in a big way.
