Caption: James Van Allen (1914-2006), US astrophysicist. Following his doctorate in 1939, he began work on photodisintegration before developing proximity fuses for weapons during World War II. In 1958, he argued for the use of a Geiger counter (radiation detector) on Explorer I, the first American scientific satellite. The counter detected belts of ionised particles trapped by the Earth's magnetic field, now called Van Allen belts after him. Van Allen retired in 1985 and was awarded the Crafoord Prize for Astronomy in 1989.
