Niels Bohr Biography and Timeline

Bohr Works With Rutherford In Manchester

Niels Bohr joined the laboratory and drew on its nuclear research while developing quantum atomic ideas. The development made new measurements available to physical science.

Discovery of Electrons

In 1913, Danish physicist Niels Bohr postulated that electrons resided in quantized energy states, with the energy determined by the angular momentum of the electrons orbits about the nucleus

Bohr Returns To Manchester Physics

Bohr accepted a university appointment and continued discussion of atomic theory with Rutherford's group. The project contributed to an expanding network of engineering expertise.

Nobel Prize

Receives the Nobel Prize in Physics for investigations of atomic structure and the radiation emitted by atoms.

Compound Nucleus Theory

Develops the compound-nucleus picture used to understand neutron capture and nuclear reactions.

Fission Theory

Carries news of uranium fission to the United States.

Role range: 1885-1962

Uranium Fission Theory

With John Wheeler, develops a theoretical account of nuclear fission and isotope-dependent neutron behaviour.
