Norwegian-born violinist and choral conductor in the Lutheran choral tradition. (April 1, 1871-June 1, 1955)

In 1901, Christiansen was recruited by St. Olaf College president John N. Kildahl. The St. Olaf Choir was founded as an outgrowth of the St. John’s Lutheran Church Choir in Northfield. For the next 30 years, Christiansen led the St. Olaf Choir, striving for perfect intonation, blend, diction and phrasing. He was a skilled conductor, directing bands and choirs alike. He assumed direction of the St. Olaf Band in 1903.

Christiansen was considered a pioneer in the art of a cappella (unaccompanied) choral music. Christiansen composed and arranged over 250 musical selections and his choral techniques were spread throughout the U.S. by St. Olaf graduates.
