Enrico Fermi, one of the pre-eminent physicists of the atomic age and winner of the Nobel Prize for physics in 1938, will be honored on a stamp on the centenary of his birth on Sept. 29, 1901.

For his discovery of nuclear reactions brought about by slow neutrons, Fermi was awarded the Nobel Prize in physics in 1938. In 1942, as part of the Manhattan Project, he directed the first controlled and self-sustaining man-made nuclear chain reaction.
