1885-Niels Bohr
Niels Bohr was born in Copenhagen -
1913-Niels Bohr Quantum Theory
In 1913, Bohr introduced what is known as the Bohr Atomic Model. His quantum theory was that that energy is transferred only in certain well defined quantities. He thought that electrons should move around the nucleus, but only in prescribed orbits.

1927-Complimentarity Theory
Bohr proposed that regarding the distinction between waves and particles, they complementary ways of understanding reality in which neither one is more real than the other. This would later become essential in quantum mechanics.

1930-Discussion of Stellar Energy
In 1930, Niels Bohr presented the idea of law of energy conservation. He believed that non-conservation in the nuclear domain applied to stars, which would indicate a problem with fundamental physics. While largely ignored by astrophysicists at the time, his theory is starting to be reviewed more lately.

1945-Manhattan Project
While information is brief and not readily available, Niels Bohr did work with other esteemed scientists on the Manhattan Project. There are articles that describe Bohr as regretful for the tragedy that took place after the Manhattan project was finished.
