  • Period: to

    Continued Education

    Bohr received his master's and doctorate degree in physics focused on electron theory of metals. His thesis was awarded in April 1911.His dissertation did not receive much attention as it was written in Danish as requirement from Copenhagen University.
  • Legacy: The Bohr Model

    Legacy: The Bohr Model
    Bohr contributed to Rutherford's atomic theory of 1912 that atoms contain protons and electrons. He took the theory a step further by creating a bohr model built on the hydrogen atom. His atomic theory stated that electrons leap through levels and have less energy the closer they are to the nucleus. This quantum theory helped explain why elements have different properties.
  • Nobel Prize Winner

    Nobel Prize Winner
    Bohr was recognized for his contribution to understanding the atomic structure. He was awarded for his early 1913 trilogy essays on atomic theory. His theories set a great foundation in creating the periodic table since he emphasized on the importance of electrons on creating different properties.
  • Death

    Bohr died at 77 from a heart attack in his hometown on November 18, 1962. His ashes were buried in Assistens Cemetery along his parents and siblings. His wife's ashes were also buried there when she died.
