Born 9 Jul 1926.American-Danish physicist, born in Chicago, Ill., who shared the 1975 Nobel Prize for Physics with Aage N. Bohr and James Rainwater for "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection."

Later research investigated the fact that nuclear matter has properties reminiscent of superconductors.
