"Wernher Magnus Maximilian, Freiherr von Braun" was a German and American aerospace engineering/aerospace engineer and space architecture/space architect. He was one of the leading figures in the development of rocket technology in Germany and the United States. He is considered one of the "Fathers of Rocket Science". He was also a member of the Nazi party and the Schutzstaffel/SS, and was suspected of perpetuating war crimes during World War II.

In his twenties and early thirties, von Braun was the central figure in the Nazis' rocket development program, responsible for the design and realization of the V-2 rocket during World War II. After the war, he and select members of his rocket team were taken to the United States as part of the secret Operation Paperclip. Von Braun worked on the United States Army intermediate range ballistic missile (IRBM) program before his group was assimilated by NASA. Under NASA, he served as director of the newly formed Marshall Space Flight Center and as the chief architect of the Saturn V launch vehicle, the superbooster that propelled the Apollo spacecraft to the Moon. According to one NASA source, he is "without doubt, the greatest rocket scientist in history". In 1975 he received the National Medal of Science.
