Andrew C. Olson was born in January of 1876 in Norway and came to America in 1892. By 1899 he and Wallace D. Barnes had opened a studio at 224 N.P. Avenue in Fargo, but the partnership did not last long. According to the 1900 Fargo city directory, Olson boarded at 414 Fourth Street North in Fargo. In the 1900 census, a Mike Olsen is listed at the same address, likely the same person.
Mr. Olson operated his own studio until 1902, moving to the Smith Block at 25 Broadway for a short time.
