| Niels Henrik David Bohr was born in Copenhagen on October 7,1885, as the son of Christian Bohr, Professor of Physiology at Copenhagen University, and his wife Ellen. Niels, together with his younger brother Harald, grew up in an atmosphere most favorable to the development of his gift-his father was a great physiologist, who encouraged his interest in physics while he was still at school, and his mother came from a family successful in the field of education. In 1903, Bohr entered Copenhagen University where he came under the guidance of Professor C. Christiansen, a highly gifted physicist, and gained his master's degree in physics in 1909 and two years later his doctorate. While still a student, the announcement by the Academy of Sciences in Copenhagen of a prize to be awarded for the solution to a certain scientific problem, caused him to conduct an experimental and theoretical investigation of surface tension (表面张力). This work, which he carried out in his father's laboratory and for which he received the prize offered (a gold medal), was published in the Transactions of the Royal Society in 1908. In the autumn of 1911 he went to Cambridge University, where he profited by following the experimental work going on in the Cavendish Laboratory under Sir J. J.Thomson's guidance. In 19131914 Bohr held a lectureship in physics at Copenhagen University and in 19141916 a similar appointment at the Victoria University in Manchester. In 1916 he was appointed Professor of Theoretical Physics at Copenhagen University, and from 1920 (until his death in 1962) he was the head of the Institute for Theoretical Physics, established for him at that university. 1.
