Niels Bohr's Model of the Atom in 1913 (7 Oct 1885 - 18 Nov 1962)
In 1913 Bohr spotted a problem in Ernest Rutherford's speculation of the way neutrons orbited a nucleus. Bohr knew that a moving charged particle would give off electromagnetic radiation, and it would lose some of that energy as a result. If Rutherford's theory was used, the electron would eventually collide and destroy the atom. Bohr found that electrons have energy levels so they can absorb and emit energy. This improved our model of the atom, which we still use to this day, the Bohr Atom. -

Niels Bohr Received the Nobel Prize in 1922 (7 Oct 1885 - 18 Nov 1962)
In 1922 Bohr was recognized for his work on atomic structure and he won the Nobel Prize in Physics. He was awarded "for his services in the investigation of the structure of atoms and of the radiation emanating from them (Nobel Media AB). Following this massive achievement he continued investigating "the constitution of atomic nuclei, including their transformations and declensions" (Bohr, Niels Collection). -
Niels Bohr Formulated the Complementarity Principle in 1927 (7 Oct 1885 - 18 Nov 1962
In 1927 Bohr founded the Complementarity Principle which stated that atomic phenomenons will express differently based on how they are observed. Depending on how the experiment is arranged, the behavior of such phenomenon as light and electrons sometimes wave-like and other times particle-like It is impossible to observe them both at the same time. Examples of these include wave length duality. This formed the basics of early Quantum Theory. -
Neils Bohr Discovers Nuclear Fission in 1939 (7 Oct 1885 - 18 Nov 1962)
In 1939 Bohr announced a groundbreaking discovery that would later revolutionize the creation of weapons of mass destruction. He found that when a uranium atom is split it releases millions of volts of energy. At the time Bohr did not realize that his work would eventually lead to mass destruction. He believed that this knowledge should be shared with other countries and he spent his remaining years promoting the peaceful use of atomic physics.
