Aribert Heim was a Nazi doctor at the Mauthausen concentration camp. He gained notoriety there for operating on healthy patients, often killing them painfully in the process. Heim, however, evaded prosecution after World War II, spending the last 30 years of his life on the run and ultimately dying in Cairo in 1992. Nicholas Kulish, co-author of The Eternal Nazi, tells the story.
