Dr. Edward Richtofen (Biography)

"Beware The Doc". A message that was scrawled across walls of every town under Axis control. Starvation may cripple you, dysentery may wreck you, and gunfire may rip the flesh from your bones, but "Beware The Doc".
This is Dr. Richtofen, known affectionately as "The Butcher" to his victims as they scream in agony moments before he snuffs out their light. All through his career, Richtofen has been at the forefront of torture and information extraction research. Richtofen is an incurable sociopath and sees no moral distinction between natural death and murder; the victim is the victim, regardless of how their demise manifests itself.

Doctor Richtofen has a collection of stuffed animals, most of them posed in positions of terror at the instant of their imminent death.

Dr. Edward Richtofen studied at Heidelberg University, where Ludvig Maxis tried to be a father figure to him, as the death of his parents affected him greatly.
