Rainwater, (Leo) James(1917–86) physicist; born in Council, Ida. He taught at Columbia University (1939–42), worked on the Manhattan Project (1942–46), then returned to Columbia (1946–86). With Aage Bohr and B. R. Mottelson, he produced a nuclear model unifying the two prevailing theories of nuclear structure. The three shared the 1975 Nobel Prize in physics for this work.
