Niels Bohr's father was Christian Bohr and his mother was Ellen Adler. Christian Bohr was awarded a doctorate in physiology from the University of Copenhagen in 1880 and in 1881 he became a Privatdozent at the university. Late in the same year he married Ellen, who was the daughter of David Adler, a Jewish politician with a high standing in Danish political and commercial life. Christian and Ellen had three children. The eldest was Jenny born in 1883 in the mansion which David Adler had owned opposite Christiansborg Castle where the Danish Parliament sat. Ellen's mother had continued to live in this house after her husband David Adler died in 1878 and Ellen had gone back to her mother' home to have her child.

Niels Bohr's home was one filled with openness and refinement. He lived in the home with his parents and his younger brother, Harald, and his older sister Jenny. Niels' home was not only intellectual, but which was ... among the most distinguished in outlook and humanity. Christian and Ellen Bohr were to a rare degree able to give their children an education. This education opened up the children's possibilities for success. As a child Niels was always very interested in working with his hands in practical activities.

In 1913, Niels Bohr developed a new theory of the atom that built on the "Rutherford model," which viewed the atom as a compact nucleus surrounded by many lighter electrons. Bohr's new theory advanced the idea that electrons travel only in certain orbits and that a particular atom can exist only in a discrete set of stable states. Further, an atom's outer orbits, which can hold more electrons than inner orbits, determine the atom's chemical properties. In his theory, Niels Bohr speculated that atoms emit electromagnetic radiation when an electron jumps from an outer orbit to an inner one. At first, his theory met with skepticism, but by 1922 it had become accepted, earning him the Nobel Prize. Other physicists would later expand Bohr's theory into quantum mechanics.

The Niels Bohr Archive (NBA) holds primary material for the history of modern physics, pertaining in particular to the early development of quantum mechanics and the life and career of Niels Bohr (1885-1962). Although the NBA has existed since shortly after Bohr's death in 1962, its future was only secured at the centennial of Bohr's birth in 1985, when a deed of gift from Bohr’s wife, Margrethe, provided the opportunity to establish the NBA as an independent not-for-profit institution. Since 1985, the NBA has had its own board of directors and has received a fixed annual sum for running expenses, presently from the Danish Ministry of Science, Technology and Innovation; the NBA has ... made ample use of its privilege to apply for project support from private sources.

Niels Bohr was born in Copenhagen Denmark on October 7, 1885. His compulsory education was completed in Copenhagen and he ... entered the University of Copenhagen in 1903. As a student in 1908, Bohr received his first award of many to come, for an investigation of the surface tension using oscillating fluid jets. This award was offered by the Academy of Sciences in Copenhagen and Bohr received the first place prize. Bohr completed his Master’s in Physics in 1909 and his Doctorate in 1911, with Studies on the electron theory of metals as his thesis. Bohr’s primary research was done in Manchester under Professor Rutherford.

Niels Bohr was born in Copenhagen on October 7, 1885. He was the older of the two sons born to Christian Bohr and Ellen, née Adler. His father was a Professor of Physiology at Copenhagen University. In his early childhood his father helped to cultivate his interest in physics. Niels attended Gammelholm Grammar School until 1903, when he enrolled in Copenhagen University. It was at Copenhagen University where he met Professor C. Christiansen.
