James Alfred Van Allen (September 7, 1914 – August 9, 2006) was an American space physicist at the University of Iowa. He was instrumental in establishing the field of magnetospheric research in space.
The Van Allen radiation belts were named after him, following his discovery using Geiger–Müller tube instruments on the 1958 satellites (Explorer 1, Explorer 3, and Pioneer 3)[2][3][4] during the International Geophysical Year. Van Allen led the scientific community in putting scientific research instruments on space satellites.
