| Bemærkning | Harald Bohr (1887 - 1951) was a Danish mathematician and brother of Niels Bohr.
Harald studied mathematics at the University of Copenhagen. He entered the University in 1904 and quickly became a well known Danish personality, not for his mathematics but rather for his soccer skills. He was in the Danish football team which was placed second in the 1908 Olympic games in London. he became professor of mathematics in the Polytechnic Institute in Copenhagen in 1915. Then, in 1930, he was appointed professor of mathematics at the University of Copenhagen. Harald Bohr worked on Dirichlet series, and applied analysis to the theory of numbers. Bohr's interest in which functions could be represented by a Dirichlet series led him to devise the theory of almost periodic functions. He founded this theory between the years 1923 and 1926 and it is with this work that his name is now most closely associated. James Franck (1882-1964) was a German physicist and winner of the 1925 Nobel Prize for Physics. He emigrated to USA in 1936. During the Manhattan Project, Franck served as Director of the Chemistry Division of the University of Chicago's Metallurgical Laboratory. He also served as chairman of the Committee on Political and Social Problems regarding the atomic bomb. The product of this committee was the Franck Report, released June 11, 1945, which recommended an open demonstration of the atomic bomb’s power in an uninhabited locality rather than dropping the bomb on Japanese cities. Franck worked the institute in Copenhagen between 1920 and 1921 and again 1934 and 1935. |
