Birth Of Niels Bohr
On October 7, 1885 Niels Bohr was born in Copenhagen, Denmark. His mother was Ellen Adler, who was part of a successful Jewish banking clan. His father Christian Bohr, was a physiology academic. His father became a professor of physiology at the University of Copenhagen and was nominated Nobel Prize twice. -

Niels Bohr College Education
In 1903 Bohr was enrolled at the University of Copenhagen, where he would study physics. Bohr obtained his doctorate in 1911 with a dissertation on the electron theory of metals. -
Wedding Bells for Niels Bohr
In 1912, Bohr married Margrethe Norlund. The couple had six children, four of them survived to adulthood and, Aage, would become a well-known physics scientist as well. -
Bohrs Model
Niels Bohr introduced the atomic Hydrogen model in 1913. He described it as a positively charged nucleus, comprised of protons and neutrons, surrounded by a negatively charged electron cloud. In the model, electrons orbit the nucleus in atomic shells. The atom is held together by electrostatic forces between the positive nucleus and negative surroundings. -
Bohr Published Articles
Bohr published articles in The Philosophical Magazine in 1913, that electrons could only occupy particular orbits determined by the quantum of action and that electromagnetic radiation from an atom occurred only when an electron jumped to a lower-energy orbit. -
Establishment of Bohrs Institute
The establishment of the Institute for Theoretical Physics happened in 1921. In the inauguration speech for the institute on March 3, 1921, he stressed, first, that experiments and experimenters were indispensable at an institute for theoretical physics in order to test the statements of the theorists. -
First Nobel Prize
Bohr was awarded the Nobel Prize for his work in 1922. The Hungarian physical chemist Georg Hevesy and Dirk Coster from Holland, were working at Bohr’s institute. They were trying to establish experimentally a yet-undiscovered atomic element 72. -
Debating Quantom Theory
Bohr's theory, called quantum theory, proposed that electrons circle the nucleus following the classical laws but subject to limitations, such as the orbits they can occupy and the energy they lose as radiation when they jump from one orbit to another. But it also attempted to explain in a unified way all the quantum phenomena that had been observed to date. https://www.youtube.com/watch?v=fm2C0ovz-3M -
Atoms for peace prize
Danish physicist Niels Bohr, who has probably inspired more physicists to inspire more physicists than any living man, was chosen in March to be the first recipient of the Atoms for Peace Award, consisting of a gold medal and an honorarium of $75 000. -
Death of Bohr
Bohr was a profound writer with more than 100 publications to his name. After having a stroke, he died on November 18, 1962, in Copenhagen at the age of 77. -
