Biography
Jona was nine years old when Nazi Germany invaded Poland in September 1939. Jona and her family, residents of Łódź, were incarcerated in the Łódź ghetto, from which her parents were deported to the Chelmno extermination camp in 1942. In August 1944 she and her two sisters, including her twin, Miriam, were sent to the Auschwitz concentration camp. Mengele, not recognizing she was a twin, sent the 14-year-old Jona in the direction of the gas chambers. However, when her older sister apprised Mengele of that fact, Jona and Miriam were sent to Mengele's "laboratory" for twins research. Jona was tattooed with the number A27725 and Miriam received the number A27700. "Mengele removed organs from people without anaesthetic, and if one twin died the other would be murdered."
