    PHD
    Niels Bohr received his PHD in Physics from the University of Copenhagen.
  • "The Trilogy"

    Bohr had three papers published in "Philosophical Magazine" in July, September, and Novemberof this year. Known as "The Trilogy" he adapted Rutherford's nuclear structure to Max Planck's quantum theory and so created his Bohr model of the atom. This also created the basis of "old quantum physics".

  • Niels Bohr Institue

    Niels Bohr Institue
    Niels Bohr led a campaign to start a theoretical physics institute. After opening in 1921 this institute served as a focal point in studies of quantum mechanics and related subjects from the 1920's to 1930's.
  • Nobel Prize

    Niels Bohr was awarded the Nobel Prize "for his services in the investigation of the structure of atoms and of the radiation emanating from them"
  • Bohr–Kramers–Slater Theory (BKS)

    BKS was the final attempt to understanding the interaction of matter and electromagnetic radiation. This led to the creation of matrix mechanics, the first form of modern quantum mechanics.
  • Quantum Physics

    Starting in 1927 Bohr began adopting many new theories on quantum physics in this new phase of normal science in their current paradigm. At the Fifth Washington Conference on Theoretical Physics with Fermi on 26Jan1939 taking in account the last piece of the puzzle stated, "I have understood everything." And began a paper with John Wheeler.
  • "The Mechanism of Nuclear Fission"

    Bohr and Wheeler developed a theoretical treatment which they published in a September 1939 "The Mechanism of Nuclear Fission" (01Sep1939) Retrieved 21Jul19 https://journals.aps.org/pr/pdf/10.1103/PhysRev.56.426
  • International Atomic Energy Agency

    International Atomic Energy Agency
    Bohr suggested an "Open Letter" to the United Nations asking for international cooperation on nuclear energy. The International Atomic Energy Agency was created with Bohr's suggestions after Soviet Union's nuclear testing in June 1950.

    World War II and the Manhattan Project

    World War II was a difficult time for scientific research. While in Britain, Bohr provided refugees with jobs at his institute. On 29Sep1943 Bohr and his wife fled Denmark. Eventually making it to Britain and then New Jersey, Bohr partook in the Manhattan Project under the alias of Nicholas Baker.

    Later Years

    While the war was ending, Bohr returned to Copenhagen and was re-elected President of the Royal Danish Academy. Bohr spent the remainder of his years influencing groups such as CERN and served as a chairman of the Nordic Institute for Theoretical Physic. Bohr passed away to heart failure in his house on 18Nov1962.
