Enrico Fermi, a naturalized U.S. citizen and one of the preeminent physicists of the atomic age, was awarded the Nobel Prize in Physics in 1938 for his discovery of nuclear reactions brought about by slow neutrons. In 1944, he moved to Los Alamos, NM, to assist in the direction of the Manhattan Project's scientific team. On November 16, 1954, Pres. Dwight D. Eisenhower and the Atomic Energy Commission gave Dr. Fermi a "special award for his lifetime of accomplishments in physics and for the development of atomic energy." This stamp commemorates the centenary of his birth on September 29, 1901, in Rome, Italy.
