When the Nazis invaded Hungary in 1944, they sent virtually the entire Jewish population to Auschwitz. A Jew and a medical doctor, Dr. Miklos Nyiszli was spared from death for a grimmer fate: to perform "scientific research" on his fellow inmates under the supervision of the infamous "Angel of Death" Dr. Josef Mengele. Nyiszli was named Mengele's personal research pathologist. Miraculously, he survived to give this terrifying and sobering account.
