Niels Bohr (1885 - 1962)
Niels Bohr authored the model of an atom. He speculated that a certain amount of electrons stayed in shells around the nucleus. “This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus.” (Aaserud) -

In 1927 Niels Bohr, Werner Heisenberg and Wolfgang Pauli come up with the Copenhagen Interpretation. "The Copenhagen interpretation was the first general attempt to understand the world of atoms as this is represented by quantum mechanics." (Copenhagen Interpretation of Quantum Mechanics) Basically systems at atomic levels don't have defined properties to them until they are being measured. Which is very difficult to conceptualize. -

Niels Bohr and his colleagues first discovered fission when they spilt a uranium atom in half. When the atom was split, it released “two hundred million electron volts of energy, heralded the beginning of the atomic age.” (Niels Bohr Announces the Discovery of Fission) Later, during a conference where Bohr announced the discovery of Fission. It was realized that this process could be used to create nuclear chain reactions and weapons of mass destruction. -

Niels Bohr initially discovered the Bohr–van Leeuwen theorem.It was later rediscovered by Hendrika Johanna van Leeuwen. The theorem states "when statistical mechanics and classical mechanics are applied consistently, the thermal average of magnetisation is always zero. The corollary is that magnetism can be explained only by quantum mechanics." (Niels Bohr) This theorem is useful in various applications mostly in plasma physics.
