René Slotkin and his twin sister survived Mengele's experiments and were miraculously reunited six years after their separation.
As a physical education teacher at an Orthodox boys school in New York City, René Slotkin frequently wore short-sleeved shirts — leaving the numbers tattooed into his arm visible to anyone who saw him.
His story of Holocaust survival was remarkable: Slotkin and his sister were among just 200 sets of twins to survive gruesome experimentation by the infamous Nazi physician Josef Mengele at Auschwitz, then were reunited six years after being separated.
Born René Guttmann in 1937 in Teplice-Sanov, Czechoslovakia, René was only 3 years old when he and his twin sister Irene were deported to Theresienstadt with their mother, Ita, in 1941. (Their father Herbert was taken to Auschwitz in 1940 and died there.)
Two years later, they were moved to Auschwitz, where their mother was killed and the twins were separated and subjected to medical abuse by the infamous Nazi physician Josef Mengele.
