To this day one of the most secret USA intelligence programs, Operation Paperclip illegally brought 760 Nazi scientists to America in the wake of WWII. Many had committed numerous war crimes, including conducting biomedical experiments on humans at concentration camps and in secret Lebensborn labs.

Lebensborn, translated from archaic German as 'wellspring (or, fountain) of life', the most secret and terrifying Nazi breeding program, was launched in 1935 by the SS boss and Hitler's right-hand man, Heinrich Himmler, a member of the Thule Society.
Rooted in the mainstream genetics of reputable and most advanced scientific and technological society of its day, the aim of the project was to create "genetic purity" of the superior Aryan master race.
The Lebensborn mothers swore the SS oath, “My honour is my loyalty,” a bond of secrecy which for many proved hard to break even decades later.
