Miklós Nyiszli (1901-1956) was a Jewish prisoner at the Auschwitz concentration camp. Nyiszli, his wife and young daughter were transported to Auschwitz in May 1944. After he had worked for a short while as a labourer at the I. G. Farben factory at Auschwitz-Monowitz, his medical qualifications were discovered by the SS and he was sent to the extermination camp at Auschwitz-Birkenau, where he worked as a pathologist under the supervision of the notorious camp doctor Joseph Mengele. Nyiszli survived the camp along with his daughter and returned to his home, now part of Romania, where he died in 1956.
