The X-Files, Season 3

Byers:
Are you familiar with a post-World War II project known as Operation Paper Clip?

Mulder:
Our deal with the devil. The U.S. government provided safe haven for certain Nazi war criminals in exchange for their scientific knowledge.

Langly:
[Points at the picture.] I know who this man is. Victor Klemper.

Byers:
The man standing next to your father is one of those criminals, though not the most famous of the bunch. Wernher von Braun, designer of the V-2 rockets that leveled London, may be the most notorious, but Victor Klemper certainly takes the prize for the most... evil Nazi to escape the Nuremburg trials.

Scully:
What did he do?

Langly:
He experimented on the Jews... drowned them, suffocated them, put them in pressure chambers. All in the name of science.

Byers:
Together with Von Braun, Klemper helped us win the space race. Using his scientific data on the effects of high-altitude flying, we were able to put astronauts on the moon before the Soviets.

Langly:
One giant step for mankind.
