Reidar Holter rowed in the Ormsund Roklub’s inriggers coxed four at the 1912 Stockholm Olympics. A first place in the heats and a defeat against Sweden in the semi-final were enough to win bronze in this event.
While in Norway, Holter worked as a forwarding agent. Just one year after the Olympics, he emigrated to the United States, just like his teammate [Max Herseth]. In the last year of World War I, he served as a private in the infantry of the US Army. In the 1920s, Holter spent some years in Norway and lived as a farmer in Nannestad. He married Anna Kornelia Østby in Akershus in 1923 and had a daughter. In 1927, he returned to the United States, probably without his family.
