Ruth Cohen had a childhood filled with family, friends, Hebrew school, and swimming in the Latorica River near her home. Then, in March 1944, at age 13, everything changed. Nazi Germany invaded Hungary, and authorities later forced Ruth and her family to move into a crowded ghetto. By mid-May, they began sending Jews from Hungary by train to Auschwitz-Birkenau. Soon after arriving at the killing center, Ruth learned the SS had already murdered her mother, brother, and little cousins.
