But one such was Harald Bohr (brother of much more famous physicist, Niels), b. April 22, 1887 (d. 1951) who worked in Mathematical analysis, founding the field of almost periodic functions, co-creating the Bohr–Landau theorem, and co-editing the journal Acta Mathematlca...
His sports career included winning a sliver medal for Denmark at the 1908 London Olympics in football. Denmark lost the final to Great Britain, but prior to that we creamed France A and France B, 17-1 and 9-0, respectively. Harald Bohr scored two goals against France B.
