Louise Brunius was an author whose novels were translated into German.

Louise Brunius was born at Blombacka manor in Vinköls parish, now in Skara municipality. She was the daughter of Carl Carlson and Christina Maria Simberg. In 1823 Louise Brunius married J. N. Brunius, the son of Gomer Brunius, a dean, and who worked as a chief financial officer.

Louise Brunius made her written debut anonymously in 1841 when Elmén & Granbergs publishers in Stockholm released her novel Mariana, eller försakelsens belöning. In 1843 she published another two novels under the pseudonym of L-e, one entitled Systrarne and the other Den unga enkan i Norrland. They were reviewed in the Göteborgs Handels- och Sjöfarts-Tidning newspaper on 5 July 1843. The reviewer stated that the unknown author’s stories “reveal hints of an unmistakably feminine pen”. Both of these novels were translated into German in 1844. In 1843 she had also published a novel entitled Äktenskaps-skilnaden, again under the pseudonym of L-e. It too was translated into German in 1845. Meanwhile in 1844 her novel Slägtingarne i landsorten was published by the Lars Johan Hierta publishing house and subsequently released in German the following year. Her novel Rosen och resedan was published by Österlund & Berling in Norrköping in 1846. Louise Brunius produced another three novels, using the same pseudonym and all published by A. Cedergren publishers in Stockholm, namely: Skalden och sångerskan, En mystification, and finally I hemmet och ute i verlden.

In 1859 Louise Brunius travelled to America with her husband in order to reside with her son, Johan Oswald (John) Brunius, who lived in Minnesota. The couple returned to Sweden in 1865, shortly after which her husband died. Louise Brunius then went back to live with her son in America, remaining there until 1872. Her final novel Lyckans gunstlingar was published by F. C. Askerberg publishing house in Stockholm in the summer of 1875.

Louise Brunius died at Götala Kungsgård, in Skara congregation, in 1880.
