Starting in May 1945, more than 1,600 Nazi scientists were brought to America to continue their weapons work for the U.S. government.

They developed rockets, aviation & space medicine, chemical & biological weapons, and many others at a feverish and paranoid pace that defined the Cold War.

Among them: Dr. Konrad Schäfer (l), Dr. Siegfried Ruff (c), Dr. Hermann Becker-Freyseng (r). In Berlin, Ruff directed the German Experimental Station for Aviation Medicine. At Dachau KZ, Ruff supervised medical murder experiments authored by Schäfer and Becker-Freyseng.
