Wernher Magnus Maximilian Freiherr von Braun (US: /ˈvɜːrnər vɒn ˈbraʊn/ VUR-nər von BROWN; German: [ˈvɛʁnheːɐ̯ fɔn ˈbʁaʊn]; 23 March 1912 – 16 June 1977) was a German-American aerospace engineer and space architect. He was a member of the Nazi Party and later the Allgemeine SS which supported his rocket work. He became the leading figure in the development of rocket technology in Nazi Germany, and later a pioneer of rocket and space technology in the US.
As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde Army Research Center during World War II. The V-2 became the first artificial object to travel into space by crossing the Kármán line on 20 June 1944. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1 in 1958. He worked with Walt Disney on a series of films, which popularized the idea of human space travel in the US and beyond from 1955 to 1957.
