Short answers, pulled from the story.
Wernher von Braun was a German American aerospace engineer born on the 23rd of March 1912 in Wirsitz, Prussia. He is known for leading the development of the V-2 rocket in Nazi Germany and for serving as chief architect of the Saturn V rocket that launched Apollo 11 to the Moon in 1969.
Von Braun applied for Nazi Party membership on the 12th of November 1937 and was issued membership number 5,738,692. He also joined the SS in 1940 after being pressured by a representative of Heinrich Himmler, rising to the rank of SS-Sturmbannführer (Major) by June 1943.
Von Braun surrendered to American forces on the 2nd of May 1945 and was subsequently brought to the United States as part of Operation Paperclip. The transfer of von Braun and his specialists was approved by U.S. Secretary of State Edward Stettinius Jr. on the 20th of June 1945, as one of his last official acts.
Von Braun was the chief architect of the Saturn V super heavy-lift launch vehicle used in the Apollo program. He served as the first director of NASA's Marshall Space Flight Center from 1960 to 1970. Apollo program director Sam Phillips stated he did not believe the United States would have reached the Moon at all without von Braun's contribution.
More people died building the V-2 rockets (approximately 12,000) than were killed by them as weapons (approximately 9,000). Von Braun admitted visiting the Mittelwerk plant where slave laborers worked under brutal conditions. Multiple prisoners gave testimony that he witnessed or permitted abuses, though he denied this and stated he felt helpless to change the situation.
Von Braun died on the 16th of June 1977 of pancreatic cancer in Alexandria, Virginia, at age 65. He had been diagnosed with kidney cancer in 1973 during a routine physical examination. He is buried at Ivy Hill Cemetery in Alexandria, where his gravestone cites Psalm 19:1.
