Bohr Model
The Bohr Model, a model of the atomic structure, was developed and published - the first true visualization and understanding of the nature of the atom which was inspired by J.J. Balmer’s formula describing the spectrum of the hydrogen atom.University of Copenhagen, 2022, Niels Bohr Institute;Who, What, When – Great Danish researchers: Niels Bohr, https://nbi.ku.dk/english/www/niels/bohr/

The Correspondence Principle
The “Correspondence principle” was published and was described as any new concepts or theories pertaining to atomic phenomena that must be proven and applicable in conventional physics. He was previously known to explain it as “the relation between classical and quantum mechanics”(Bukulich).Bokulich, A and Peter Bokulich, "Bohr’s Correspondence Principle", The Stanford Encyclopedia of Philosophy (Fall 2020 Edition), Edward N. Zalta (ed.),

Institute of Theoretical Physics
Bohr founded the Institute of Theoretical Physics in Copenhagen to which he remained director until his death. The inspiration of the institute was in relation to poor conditions and lack of proper laboratories at the University of Copenhagen. Watch video of the current light artwork placed on the front of the institute. The artwork is directly connected to a physics experiment in Switzerland.

Nobel Prize
Bohr won the Nobel Prize in Physics alongside Albert Einstein, Ernest Rutherford and Max Planck for their work in nuclear physics, a newly accepted concept for the Nobel Foundation.University of Copenhagen, 2022, Niels Bohr Institute;Who, What, When – Great Danish researchers: Niels Bohr, https://nbi.ku.dk/english/www/niels/bohr/

The 5th Solvay Conference
Bohr's Complementarity concept was a consensus-based result of the Solvay Conference where 29 world famous physicists met to discuss quantum theory. Einstein and Bohr had deep debates about the relationship between relative and quantum mechanics. https://www.youtube.com/watch?v=8GZdZUouzBYUniversity of Copenhagen, 2022, Niels Bohr Institute;Who, What, When – Great Danish researchers: Niels Bohr, https://nbi.ku.dk/english/www/niels/bohr/

"Liquid drop" concept
The “liquid drop” model was developed thus leading to the understanding of nuclear fission and explaining the force needed to create the splitting of an atom.Bohr, N. (1934): Atomic theory and the description of nature. Cambridge University Press, Cambridge UK.

World War II
Bohr flees to Sweden, England and America from invading German forces who wanted Bohr for their own nuclear research during World War II. The Germans consequently occupied the Institute of Theoretical Physics.University of Copenhagen, 2022, Niels Bohr Institute;Who, What, When – Great Danish researchers: Niels Bohr, https://nbi.ku.dk/english/www/niels/bohr/
