Magnus von Braun (1919–2003) was a German-born chemical engineer and rocket specialist who worked on the development of the V-2 rocket during World War II. The younger brother of famed rocket scientist Wernher von Braun, he surrendered to American forces in 1945 and subsequently came to the United States under Operation Paperclip. He joined the German rocket engineering team working with the U.S. Army at Fort Bliss, Texas, contributing to the early development of American rocket technology. His career connected the pioneering German rocket programs of World War II with the emerging American space and missile programs of the postwar era.
