Wernher von Braun
A German, he was the forerunner of rocket/(v2) research in Nazi Germany. Later, he migrated to the United States and became the Head of Rocket and Space Technology there. Rather than an aerospace engineer, he is called a space architect because the Saturn V rocket that brought man to the moon is his creation. A rare picture of him posing in front of the five powerful F-1 engines of his creation, the Saturn V rocket, before carrying humans to the moon.
