Dr. Joseph Mengele
At Auschwitz, Mengele did a number of studies on twins. After an experiment was over, the twins were usually killed and their bodies dissected. He supervised an operation by which two Roma children were sewn together to create conjoined twins.
Mengele became a German infantry soldier as he moved west. As he moved west away from the Russians, he also did work at camps at Gross-Rosen and Matthausen. Mengele was captured as a German infantry soldier near Munich.
In 1979, while swimming in the sea in Brazil, Mengele suffered a stoke and drowned. He was buried as 'Wolfgang Gerhard' at Embu.
