Hanson taught at Willmar Seminary in Willmar, Minnesota, 1885-1887, before returning to Luther College to teach music and mathematics from 1888-1890. Hanson served as principal of Decorah School of Music in 1889 which was incorporated into the Luther College the following year. Hanson left Luther in 1891 to studied music in Weimar, Germany from 1891-1892. Returning to Luther College in 1894, he was appointed as the first professor of music in 1895. He continued to serve on the faculty until 1904. Hanson served as organizer and conductor of the Luther College choirs from 1882-1883. He organized the Decorah Choral Union in 1889. In 1895 Hanson started the Luther College Musical Union. In October 1895, Hanson was placed in charge of the museum at Luther College where he served as Curator until 1902. Ultimately Hanson resigned his appointment at Luther in 1904 at least in part because of his disagreement with President CollegeChristian Keyser Preus. Hanson moved to Chicago where he became a book and music dealer, publisher and author. He was proprietor of the Northern Book and Music Company which published the monthly Norwegian-American magazine, Idun: Tidsskrift for Literatur, Musik, etc. Hanson served as its editor during the magazine’s run from 1908-1910. Among Hanson’s other activities was his service on the editorial staff of the Norwegian-American newspaper, Skandinaven. In 1904 he compiled an index to Maanedstidende and Kirketidende,the church paper for the Norwegian Synod. The first edition of an English-Norwegian-Danish dictionary compiled by Hanson was published in 1909 and reprinted in several subsequent editions. In 1916, he composed a Cantata for Christmas-tide and formulated the Norsk-Amerikansk Julebog in 1921. He also translated a poem by Henrik Ibsen titled Terje Vigen. After Hanson’s death, his library collection of Norwegian Americana was donated to the Luther College Library. The Personal Papers and records of Haldor J. Hanson can be found in the Luther College Archives in the Preus Memorial Library.
