![]() Bohr also introduced the idea that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy. On the basis of Rutherford’s theories, Bohr published his model of atomic structure in 1913, introducing the theory of electrons traveling in orbits around the atom’s nucleus, the chemical properties of the element being largely determined by the number of electrons in the outer orbits. He then went on to study under Ernest Rutherford at the University of Manchester in England. As a post-doctoral student, Bohr first conducted experiments under J. His essay won the prize, and it was this success that decided Bohr to abandon philosophy and adopt physics.Īs a student under Christian Christiansen he received his doctorate in 1911. In 1905, prompted by a gold medal competition sponsored by the Danish Academy of Sciences and Letters, he conducted a series of experiments to examine the properties of surface tension, using his father’s laboratory in the university, familiar to him from assisting there since childhood. In 1903 Bohr enrolled as an undergraduate at Copenhagen University, initially studying philosophy and mathematics. ![]() Niels Bohr was a passionate footballer as well, and the two brothers played a number of matches for the Copenhagen-based Akademisk Boldklub. His brother was Harald Bohr, a mathematician and Olympic footballer who played on the Danish national team. His father, Christian Bohr, a devout Lutheran, was professor of physiology at the University of Copenhagen (it is his name which is given to the Bohr shift or Bohr effect), while his mother, Ellen Adler Bohr, came from a wealthy Jewish family prominent in Danish banking and parliamentary circles. Bohr has been described as one of the most influential physicists of the 20th century.īohr was born in Copenhagen, Denmark in 1885. Bohr married Margrethe Norlund in 1912, and one of their sons, Aage Niels Bohr, grew up to be an important physicist who, like his father, received the Nobel prize, in 1975. He was also part of the team of physicists working on the Manhattan Project. Bohr mentored and collaborated with many of the top physicists of the century at his institute in Copenhagen. ![]() Bohr has been described as one of the most influential scientists of the 20th century.īohr made fundamental contributions to understanding atomic structure and quantum mechanics for which he received the Nobel Prize in Physics in 1922.
