In 1903 Bohr enrolled as an undergraduate at Copenhagen University, initially studying philosophy and mathematics.
In 1912 he met and later joined Ernest Rutherford at Manchester University, where on and off he spent four fruitful years in association with the older physics professor.
Karl Herzfeld - This paper was published in 1912, shortly before Niels Bohr submitted his first paper on the Bohr model of the hydrogen atom
Optics - In 1913 Niels Bohr showed that atoms could only emit discrete amounts of energy, thus explaining the discrete lines seen in emission and absorption spectra
Atom - Meanwhile, in 1913, physicist Niels Bohr suggested that the electrons were confined into clearly defined, quantized orbits, and could jump between these, but could not freely spiral inward or outward in intermediate states
In 1918 he began efforts to establish the University Institute of Theoretical Physics, which he later directed.
With the assistance of the Danish government and the Carlsberg Foundation, he succeeded in founding the Institute of Theoretical Physics in 1921, of which he became director.
Ernest Rutherford - In 1921, while working with Niels_Bohr, Rutherford theorised about the existence of neutrons, which could somehow compensate for the repelling effect of the positive charges of protons by causing an attractive nuclear force and thus keeping the nuclei from breaking apart.
In 1944 he obtained an audience with Winston Churchill, who became worried about whether Bohr was a security risk.
Tetra Pak - Upon visiting the Tetra Pak factory in Lund in the 1950s, Danish physics professor and Nobel Prize laureate Niels Bohr allegedly claimed to "never have seen such an adequate practical application of a mathematical problem" as the tetrahedron package and the innovation of the milk tetrahedron, the basis for Tetra Pak, has indeed given rise to differences in view as to who is to be credited for the invention
Curtis J. Humphreys - Humphreys attended the Rydberg Centennial Conference on Atomic Spectroscopy in 1954, which at the time was the most distinguished group of spectroscopic and atomic physicists ever assembled, and included the eminent Niels Bohr
In 1957, while the author Robert Jungk was working on the book Brighter Than a Thousand Suns, Heisenberg wrote to Jungk explaining that he had visited Copenhagen to communicate to Bohr the views of the German scientists, that production of an atomic weapon was possible with great efforts and this raised enormous responsibilities on the worlds scientists on either side.
Werner Heisenberg - Documents relating to the Bohr-Heisenberg meeting were released in 2002 by the Niels Bohr Archive and by the Heisenberg family
