Based on exclusive, unrestricted access to over 5000 pages of personal writings & family photos, this definitive biography of German physician & SS-Hauptsturmfubrer Josef Mengele (1911-79?) probes the personality & motivations of Auschwitz's "Angel of Death." From 5/43 thru 1/45, Mengele selected who would be gassed immediately, who would be worked to death, & who would serve as involuntary guinea pigs for his spurious & ghastly human experiments (twins being his particular obsession). With authority & insight Posner & Ware examine the entire life of the world's most infamous doctor.
