Bohr’s Atomic Model
Niels Henrick David Bohr (1885–1962) was born in Copenhagen, Denmark. He received his Ph.D. from Copenhagen University in 1911. Afterwards, he moved to England, where he studied under J.J. Thomson in Cambridge and under Ernest Rutherford in Manchester. Bohr’s model of the atom, based on Rutherford’s planetary model, was published in 1913. He was awarded the Nobel Prize for physics in 1922 “for his services in the investigation of the structure of atoms and of the radiation emanating from them.” He went on to serve as a professor at the University of Copenhagen and then as the director of the newly founded Institute of Theoretical Physics. He also served a minor role in the Manhattan project during World War II, after which he became a leading advocate for the peaceful use of nuclear energy. Among his most famous writings are a series of philosophical essays in which he clarified the meaning and the significance of the new atomic theory.
