James Van Allen


born 1914 died 2006
-developed the first plans for an International Geophysical Year (IGY); a coordinated, international, and comprehensive study of Earth for an 18-month period from July 1957 through December 1958. This first integrated study of Earth as a planet ushered in the space age by providing the model for large-scale, government-funded science, and because the United States and the Soviet Union included the first satellite launchings in their contributions. Van Allen's instruments were aboard the first successful American satellites, Explorers 1 and 3, launched in 1958, and provided data for the first space-age scientific discovery: the existence of a doughnut-shaped region of charged particle radiation trapped by Earth's magnetic field.
