The poster is a black and white drawing portrait of the great scientist Niels Bohr.

Danish physicist, Nobel Prize in Physics in 1922, Niels Bohr contributed to the invention of quantum mechanics with Albert Einstein and Max Planck. He proposed a new model of atoms as nuclei around which electrons gravitate at various orbits that correspond to energy levels.

Biography of Niels Bohr

Niels Bohr, born on October 7, 1885 in Copenhagen is a Danish physicist who marked the physics of the 20th century by his work on quantum mechanics with its atomic model. His studies on atomic and nuclear physics make him one of the great scientists of our time.

Born to Christian Bohr, a professor of medicine and rector of a Lutheran university, and Ellen Adler of Jewish origin, Niels Bohr was the second child of three siblings. He was the second child of three siblings. He became interested in science very quickly and entered the University of Copenhagen in 1903.

In 1906, he worked on the subject of the vibrations of a liquid jet and his thesis was awarded a prize by the Royal Danish Academy of Sciences and Letters.

In 1911, Niels Bohr became a doctoral student at the University of Copenhagen and devoted his work to the development of hypotheses on the structure of the atom.

In 1913, he published in the Philosophical Magazine a model of the structure of the atom, based on Rutherford’s theories. According to this theory, the atom is like a nucleus around which electrons gravitate in stable orbits that correspond in turn to specific energy levels.

In 1916, Niels Bohr became a professor of theoretical physics at the University of Copenhagen and then founding director of the Institute of Theoretical Physics in 1920.

Two years later, he was awarded the Nobel Prize in Physics for his studies of atomic structure and the radiation that comes from it. He then devoted himself to his institute with famous students such as Werner Heisenberg and Wolfgang Pauli.

Niels Bohr had six children with Margrethe Norlung whom he married a few months before his thesis.

In 1943, the scientist fled Denmark and returned to Copenhagen after the war.

He campaigned for the peaceful use of nuclear energy and was awarded a prize in the American Atoms For Peace program in 1957.

He died on November 18, 1962 in Copenhagen.
