Green are a Jewish doctor named Dr. Gruenbaum, who supposedly collaborated with the Nazis during WWII, and Dr. Josef Mengele, whose trademark of coldblooded and calculating brutality has not only scarred the souls of survivors from Aushwitz, but also a countless number of victims throughout the world. Mengele's direct involvement at the infamous Aushwitz concentration camp was suspiciously downplayed during the Nuremberg Trials, and consequently no intensified effort by the U.S. and its allies was directed toward his capture.[13]

As a means to confuse serious investigators as to his whereabouts, U.S. officials would report Mengele being a non-threatening recluse in Paraguay or Brazil, or that he was simply dead (the "Angel of Death" miraculously must have come back to life at least five different times). His unprecedented research, at the expense of thousands of lives, undoubtedly was a significant bonus to U.S. interests. Besides using the pseudonym of Dr. Green, survivors knew him as Vaterchen (daddy), Schoner Josef (beautiful Joseph), David and Fairchild. A gracefully handsome man of slight stature, Mengele would disarm people with his gentle demeanor, while at other times, he would explode into violent rages.[14]

Other characteristics remembered by survivors were the cadence of his shiny black boots as he paced back and forth and his "I-love-you/I-love-you-not" daisy game. When he pulled off the last daisy petal, he would maliciously torture and kill a small child in front of the other child he was programming. Distraught survivors also recalled being thrown naked into cages with monkeys, who were trained to viciously abuse them. Evidently, Mengele enjoyed reducing people to the level of animals. He also would purposely restrain his victims from crying, screaming, or showing any excessive emotion.

Dr. D. Ewen Cameron, also known as Dr. White, was the former head of the Canadian, American and World Psychiatric Associations.
