Bohr, (Aage) Niels 1922-
Danish physicist and Nobel Prize winner

Born in Copenhagen, he was the son of the Nobel prize-winning physicist Niels Bohr. Educated at the universities of Copenhagen and London, he worked from 1946 at his father's Institute of Theoretical Physics in Copenhagen where he became Professor of Physics (1956-92). From 1963 to 1970 he was also director there and from 1975 to 1981 he was director of Nordita (the Nordic Institute for Theoretical Atomic Physics). Together with Benjamin Roy Mottelson he developed the collective model of the nucleus, which combined the quantum-mechanical shell model of the nucleus and the classical liquid drop model developed by Niels Bohr, Hans Bethe and Baron Carl von Weizs�cker to support the work of James Rainwater. This model has been developed and explains the properties of nuclei well. Aage Bohr shared the 1975 Nobel Prize for physics with Mottelson and Rainwater for this work.
