Størmer was born September 3, 1874, in Skien, Norway, the only child of a pharmacist. He studied mathematics at the University of Christiania (now the University of Oslo) from 1892 to 1897, earning the rank of candidatus realium (roughly equivalent to a Ph.D.) in 1898. He then studied with Picard, Poincaré, Painlevé, Jordan, Darboux, and Goursat at the Sorbonne in Paris from 1898 to 1900. On his return to Christiania in 1900 as a research fellow in mathematics, he married Ada Clauson, with whom he eventually had five children. He visited Göttingen in 1902, and returned to Oslo in 1903, where he was appointed as a professor of mathematics, a position he held for 43 years. After he received a permanent position in Oslo, Størmer...
