Wernher von Braun has been given many superlatives: "Columbus of space", "most important rocket scientist", "father of the moon flight". But fame as a space pioneer is only one side of his biography. Wernher von Braun (born in 1912) made a pact with the Nazi regime. During Hitler's war of annihilation, he built the V2 rocket for the dictator. Just 33 years old at the end of the war in 1945, he was able to continue his career seamlessly in the USA.
