Niels Bohr was a Nobel prize-winning physicist and humanitarian who made revolutionary theories on atomic structures.
Bohr was born on 7th October 1885, in Copenhagen. He earned a doctorate in physics in 1911 from the Copenhagen University. The discoveries of the electron and radioactivity at the end of the 19th century led to different models for the structure of the atom.
In 1913, Bohr developed his model of atomic structure, known as the Bohr model, which depicts the atom as a small, positively-charged nucleus, surrounded by negatively-charged electrons that travel in circular orbits around the nucleus, similar in structure to the Solar System.
In 1921, Bohr founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute. The element bohrium (Bh) was named after him. Niels Bohr died on 18th November, 1962.
