Niels Bohr Institute, part of the University of Copenhagen, Denmark. The Institute was founded by the Danish physicist Niels Bohr (1885-1962) in 1921 as the Institute for Theoretical Physics. Bohr won the Nobel Prize for Physics in 1922. He is best known for developing the quantum theory of electron orbitals, which stated that electrons could only occupy specific regions around an atomic nucleus. This model fitted very well with the observed spectrum of hydrogen.
