Niels Bohr: October 7, 1885 - November 18, 1962

  • College History

    In 1907 Bohr earned his bachelors degree in physics, his master's in 1909, and his doctorate in 1911. Also in 1909, he had his first publication in the PhilosophicalTransactions of the Royal Society, about water tension. He used a theoretical analysis of the properties of metal, for his dissertation, using the electron theory.
  • Updating the Atomic Model

    In 1913 Bohr published three articles in the Philosophical Magazine that detailed his changes to the atomic model that was proposed by Ernest Rutherford. The articles were named, "On The Constitution of Atoms and Molecules," "Systems Containing Only a Single Nucleus," and "Systems Containing Several Nuclei."

  • Principle of Correspondence

    "In 1916, Bohr proposed the principle of correspondence, which stated that any conclusion drawn from quantum physics must not conflict with any observable phenomena" (Cullen, K. 2006).
  • Nobel Prize and Published Work

    In 1922, Bohr received the Nobel Prize in physics for his three articles developing a quantum mechanical model of the atom.
    Also in 1922, Bohr extended his atomic theory and summarized his work in "The Structure of the Atoms and the Physical and Chemical Properties of the Elements."

  • Concept of Complementarity

    In this concept, he stated that a classical description of an atomic phenomenon required two complementary phenomena.
  • World War II and the Manhattan Project

    In 1943 fled from Europe to the United States and consulted on the Manhattan Project, which created the first Atomic Bomb.
