Like those people in the syllabus.
Wehrner von Braun - the nazi person who made the V2 rocket and later american who designed rockets for space exploration for nasa. The Redstone Rocket which was used on launching of the first satellite and he oversaw the missions to the moon as director of Nasa I think. Thats his contribution.
Robert Goddard was another pioneer of rocketry but I didn't do my assignment on him.
