John Archibald Wheeler's work with Niels Bohr and Edward Teller helped advance the processes of nuclear fission and fusion. Wheeler conducted a variety of military research in association with the Manhattan Project, the effort which developed the atomic bomb during World War II, and also was instrumental in the creation of the hydrogen bomb. A professor of physics and director of the Center for Theoretical Physics at the University of Texas at Austin, Wheeler added the term "black hole" to astronomy dictionaries. Throughout his career, Wheeler has made fundamental contributions to the studies of nuclear structure, nuclear fission, scattering theory, relativity, geometrodynamics, and other subjects. A long-time professor at Princeton University, his students include the Nobel-honored physicist Richard P. Feynman. Wheeler was born in Jacksonville, Florida, on July 9, 1911. His parents, Dr. Joseph Lewis Wheeler and Mabel Archibald Wheeler, were both librarians. Dr. Wheeler was later head of the...
