Bohr attended the University of Copenhagen from 1903-1911. In his last year of attendance, he obtained his doctorate with his dissertation on the electron theory of metals.

Niels Bohr begins his postdoctoral research with Ernest Rutherford at the University of Manchester in England. He begins to develop his atomic model theory: https://www.youtube.com/watch?v=Awxcl-RwWsk

Bohr publishes several articles in the Philosophical Magazine Publication of which he postulated that electrons could only move in certain orbits. He suspected that this phenomenon was determined by the quantum of action and that the electromagnetic radiation from an atom could occur only when an electron moved to a lower energy orbit.

With the substantive research conducted by Bohr and published in the Philosophical Magazine, he was able to establish recognition for his atomic theory. Although, most physicists and other scientists found his research to be too radical or unacceptable to other research contemporary to his time. His model accounted for the structure of atoms with quantum physics. Kragh, Helge. Niels Bohr and the quantum atom: The Bohr model of atomic structure 1913-1925. OUP Oxford, 2012.

Bohr worked for many years as a professor of physics while also pursuing his personal research in quantum physics.
-
Bohr created a very complex model of building and organizing the periodic table of elements. His table relied on the addition of electrons one after another to the atom which created a series of real elements categorically arranged in one chart. Bohr, Niels. "Niels Bohr." Collected works 5 (1985).

At a conference in Como, Italy, Bohr presents his Complementarity Principle which described how at the atomic level, a physical phenomenon expresses itself differently depending on the experimental design used to study such activity. Stephenson, William. "William James, Niels Bohr, and Complementarity: I—Concepts." The Psychological Record 36.4 (1986): 519-527.

In the 1930s, Bohr contributed to the Rockefeller Foundation's experimental biology program, where he helped build a cyclotron (see image provided). This device was used for investigations with nuclear physics and the production of isotopes of elements found in organic processes. Aaserud, Finn.

Bohr joined a committee that was focused on getting physicists and other intellectuals out of Germany during WWII, who were mostly of Jewish descent. Aaserud, Finn.
