At the start of the 21st century, Aribert Heim was the most wanted Nazi criminal, second only to Alois Brunner (Bio Brunner). As physician in concentration camp Mauthausen, he performed gruesome experiments on human guinea pigs. In October 2005, rumors went around he had been traced in Spain but afterwards, there was no trace of him. In 2012, Heim was officially declared dead by German authorities: he allegedly had died in Egypt as early as 1992.
Aribert Heim was born June 28, 1914 in Radkersburg, the son of an inspector of the gendarmerie (police). The Heim family moved to Graz later on. In 1935 Aribert Heim joined the illegal Austrian branch of the N.S.D.A.P. (National Socialist German Workers Party) and the SA (Sturmabteilung). He studied medicine at Graz university. After the AnschluŖ, the university was "arisiert"(Arianized): professors, assistants and collaborators who did not openly side with the Nazi party were fired and the name was changed to "Adolf Hitler Universitšt." (Bio Hitler) The faculty of medicine was expanded with a SS medical academy, headed by SS-ObersturmbannfŁhrer Hans Kšther. In addition to lectures on medical subjects, lessons on military discipline and the Nazi ideology formed part of the curriculum. Thus, the foundation of Heimís Nazi career was laid during his time as a student.
In 1940, Heim was awarded his MD. In the spring of that year he voluntarily joined the Waffen-SS and was named camp physician in Sachsenhausen. In June 1941, he was transferred to Camp Buchenwald and subsequently to Oranienburg. October 1 of the same year he was transferred again, this time to Mauthausen. The inmates of his camp called him Doctor Death. In the two years he was employed in Mauthausen, he conducted experiments on human guinea pigs no less horrific than those of Joseph Mengele in Auschwitz. Many of his "patients" did not survive their stay in the sick bay.
