The SS troops marched the doomed prisoners to the head of the ramp onto which they had exited. They were led before an SS officer who, in the midst of all the madness, agony and death, seemed very out of place. His handsome face was set with a kind smile, his uniform impeccably tailored, cleaned and pressed. He was cheerfully whistling an opera tune, one of his favorites by Wagner. His eyes betrayed nothing but a cursory interest in the drama that was unfolding before him, the drama of which he alone was the chief architect. He carried a riding crop, but rather than using it to strike the prisoners as they passed before him, he merely used it to indicate which direction he selected them to go in, links oder rechts, left or right. Unbeknownst to the prisoners, this charming and handsome officer with the innocuous demeanor was engaging in his favorite activity at Auschwitz, selecting which new arrivals were fit to work and which ones should be sent immediately to the gas chambers and crematorium. Those sent to the left, roughly 10 to 30 percent of all new arrivals, had their lives spared, at least for the moment. Those sent to the right, usually 70 to 90 percent of all new arrivals, had been condemned to die without even a passing glance from their judge and jury at Auschwitz. The handsome officer who held omnipotent sway over the fate of all the camp’s prisoners was Dr. Josef Mengele, the Angel of Death.
