Arthur Rudolph

Arthur Louis Hugo Rudolph was a German rocket engineer who was a leader of the effort to develop the V-2 rocket. After World War II, the United States government's Office of Strategic Services (OSS) brought him to the U.S. as part of the clandestine Operation Paperclip, where he became one of the main developers of the U.S. space program. He worked within the U.S. Army and NASA, where he managed the development of several systems, including the Pershing missile and the Saturn V Moon rocket. In 1984, the U.S. government investigated him for war crimes, and he agreed to renounce his United States citizenship and leave the U.S. in return for not being prosecuted.
