 | | Leo Szilard (1898-1964), a native of Budapest and naturalized US citizen elected to the Academy in 1961, was noted for his contributions to the fields of thermodynamics, biophysics, nuclear physics, and the development of atomic energy. |
 | | Szilard, experimenting in collaboration with Fermi, Zinn, and Anderson, proved the possibility of a nuclear chain reaction, but he may be best known for his role in the initiation of the Manhattan Project for developing the atomic bomb during World War II. |
 | | In 1945, when the Project had produced an atomic bomb, Szilard circulated a petition, signed by a number of his fellow atomic scientists, asking that the bomb not be used against Japan. |
