He was raised on the Knaplundsjyen farm on the island of Knaplundsøya in Bodin Municipality (now part of Bodø Municipality). He grew up as the youngest in a family with 10 children. His parents were Martinus Johnsen Knaplund (1832–1919) and Kristina née Andreasdatter (1839–1919).
Knaplund emigrated from Norway to the United States and established his residence at Ostrander, Minnesota in the spring of 1906. He worked on the farm of Norwegian-American Hans Christensen in 1906 and 1907. Knaplund became a naturalized U.S. citizen at Red Wing, Minnesota on October 4, 1913. He graduated from Red Wing Lutheran Seminary (now St. Olaf College) with B.A. in 1913 and from the University of Wisconsin with M.A. in 1914 and with Ph.D. in 1919. He was a history teacher at Decorah High School in Decorah, Iowa from 1914 to 1916. In the history department of the University of Wisconsin-Madison, he was an assistant from 1913 to 1914 and from 1916 to 1917, an instructor from 1917 to 1921, an assistant professor from 1921 to 1925,[2] an associate professor from 1925—1927, and a full professor from 1927 to 1955, when he retired as professor emeritus.[3]
Knaplund was a Guggenheim Fellow for 6 months during the academic year 1926–1927, when he studied sources in several libraries in England.[2] He married Dorothy King of Chicago on June 19, 1926. They had two children: Katherine Barbara in 1927 and Paul William in 1928.
During the Second World War, Professor Knaplund helped Norwegians in exile in the United States. In 1953 he was made a knight of the Order of St. Olav.
He edited the foreign affairs speeches of Sir Edward Grey, British Foreign Minister at the outbreak of World War I, and much other correspondence of historical importance. Dr. Knaplund was John Hay Whitney Professor at Wells College, Aurora, N. Y., in 1955. He served as a research associate at Duke University in 1956, and as Fulbright lecturer at the United College of the West Indies in 1956‐57.[3]
Knaplund published his autobiography in 1963. It contains detailed descriptions of the conditions of Saltstraumen and its environs at the time he grew up and when he visited there in 1916 and 1923, as well as an elaboration of social identity as a Norwegian and an American.
Knaplund has his burial place in Forest Hill Cemetery in Madison. Upon his death he was survived by his widow, his son, his daughter, and six grandchildren.[3]
