| Remarks | 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. Jenny Bohr (1883 - 1933) was the elder sister of Niels and Harald Bohr. |
