For his basic contributions to our understanding of the nuclei of atoms, exemplified by his theory of nuclear fission, and his own work and stimulus to others on basic questions of gravitational and electromagnetic phenomena.

Like many great geniuses, John A. Wheeler struggled with absent-mindedness. In 1953, on an overnight train trip to Washington, D.C., Wheeler, a scientist with the Manhattan Project, lost a highly classified document detailing the hydrogen bomb’s design.rnrnThe paper was never recovered, but Wheeler’s career managed to stay intact – despite a scolding from President Dwight D. Eisenhower.rnrnWheeler helped invent nuclear fission – the process of splitting a large nucleus, the center of an atom, releasing energy.rnrnHe is best known, however, for coining the term “black hole” to describe an area of gravitational collapse often caused by dying stars.rnrn“It teaches us that space can be crumped up like a piece of paper into an infinitesimal dot, that time can be extinguished like a blown-out flame, and that the laws of physics that we regard as ‘sacred,’ as immutable, are anything but,” he wrote in his 1999 autobiography.
