Born Apr. 22, 1887, in Copenhagen; died there on Jan. 22,1951. Danish mathematician. Brother of the physicist Niels Bohr.
In 1915, Harald Bohr became a professor at the Higher Technical School and in 1930 a professor at the University of Copenhagen, where he worked on the theory of functions and theory of numbers. In connection with studies of the zeta function, he developed the theory of almost periodic functions (1923). This theory, which became an independent mathematical discipline, has numerous applications in mathematical analysis, celestial mechanics, and physics.
