Early life and education
Born on 29 January 1882 in Copenhagen, Jacobsen grew up in a rich Jewish family, the daughter of Marcus Rubin (1854–1923), director of the National Bank of Denmark, and his wife Kaja Davidsen (1854–1909). After matriculating from N. Zahle's School in 1900, she qualified as a schoolteacher in 1903. The same year she married the historian Jacob Peter Jacobsen. In 1904, she began to study Scandinavian philology at Copenhagen University where she was awarded the university's gold medal for her 1907 essay ''Naar og hvorledes har det fællesnordiske Sprog spaltet sig i forskellige Grene'' (When and how the common Nordic language broke up into different branches). After receiving her master's degree in 1908, in 1910 she became Denmark's first woman to earn a doctorate in Nordic philology with a thesis titled ''Studier til det danske Rigssprogs Historie fra Eriks Lov til Chr. III.s Bibel'' (Studies on the History of the Danish Language from Erik's Law to Christian III's Bible).Career
Realizing the limitations of further research into the Danish language owing to the absence of adequate texts and dictionaries, in 1911, thanks to the support of Kristian Erslev and Carl S. Petersen, she founded the Society for Danish Language and Literature (''Det danske sprog- og litteraturselskab'' or DSL) which she headed until 1931, whereafter she served as administrator. DSL gained importance through the publication of Jacobsen's numerous works. In collaboration with Harald Juul-Jensen (1982–1949), Jacobsen organized the work of publishing a comprehensive Danish dictionary, '' Ordbog over det danske Sprog'' which appeared in 28 volumes from 1919 to 1956. As a result of her interest inReferences
