Hermann Oberth and James Van Allen (right), space pioneers. Hermann Julius Oberth (1894-1989) was a German rocket pioneer. His books, The Rocket into Interplanetary Space (1923) and Ways to travel in Space (1929), helped establish the technology of manned spaceflight. Wernher von Braun studied under him, and both worked on the V2 rocket in the Second World War, continuing their rocket research in the USA after the war. James Alfred Van Allen (1914-2006) was a US physicist who discovered the radiation belts around the Earth, using the first US satellite, Explorer I, in 1958. Van Allen's work is covered in the book he wrote: Origins of Magnetospheric Physics (1983).
