Monday is International Holocaust Remembrance Day; so designated because January 27, 1945 was the day that the largest Nazi death camp, Auschwitz-Birkenau, was liberated by Soviet troops. We’ll mark the occasion on Thursday by revisiting a conversation with Eva Kor, a Holocaust survivor and victim of Dr. Josef Mengele’s medical experiments on twins at Auschwitz. Mengele was given the name “Angel of Death,” because of his position as a SS physician in charge of selecting which new prisoners of the camp would be killed or selected for forced labor. Kor and her sister launched a search for other twins who survived Mengele’s experiments and located 122 individual survivors.
