Olek is the young son of Henry and Manci Rosner, who is five years old at the beginning of the German occupation of Cracow. He is initially hidden so that he will not be taken to the Płaszów concentration camp, but eventually, his family decides it will be safer to smuggle him inside. He makes Oskar Schindler’s list and is transported to Brinnlitz, but he’s rounded up and shipped to Auschwitz for medical experimentation. There, however, he gets a tattoo (meaning he isn’t marked for immediate extermination), and he survives the Holocaust.
