Dieter Grau, German-American scientist and engineer (died 2014)

Dieter Grau was a German-born American aerospace engineer and member of the "von Braun rocket group", at Peenemünde (1939–1945) working on the V-2 rockets in World War II. He was among the engineers who surrendered to the United States and traveled there, providing rocketry expertise via Operation Paperclip, which took them first to Fort Bliss, Texas. Grau was sent by the U.S. Army to White Sands in 1946 to work on the assemblage and testing of the V-2. His wife joined him there in 1947. While von Braun was on standby at Fort Bliss, Grau and other German aerospace engineers busily launched V-2s for U.S. scientists to analyze. A total of 67 V-2s were launched at White Sands.
