Life

Johnsen became a student a 1896; he graduated with a master's degree in 1898, and in 1906 he received a PhD with his dissertation De norske stænder. In 1906 and 1907 he studied as a government scholar in Copenhagen, Paris, and Berlin. Later, he made a number of study trips abroad, including to England, Germany, and the Baltic countries. He was professor of history at the University of Oslo from 1913 to 1945.
Johnsen and Halvdan Koht influenced Norwegian historiography in the 1900s through their views that there was no constitutional equality between Denmark and Norway after the introduction of the absolute monarchy in AD 1660.
Together with the teachers Lorens Berg from Andebu and Jacob Aaland from Nordfjord, as well as Edvard Bull Sr., Johnsen was central to the new local historical movement that arose after the dissolution of the union. This led to the establishment of the National Society for Rural and Urban History in 1920, where Johnsen served as chairman from the its beginning until 1945. Johnsen, Berg, and Aaland worked closely together and set the standard for the modern local history book. They orientated themselves beyond the discipline of history and studied life in a small community based on source-critical studies in local and national archives.
During the Second World War, the nationally conservative Johnsen was head of the newly created Institute for Medieval Texts. The institute did not receive any special support from the Germans, but the Nasjonal Samling party was very interested in it. Johnsen was accused of cooperating too strongly with the Nazi ministry.
Johnsen was the editor of the journal Heimen from 1922 to 1945 and the editor of the local history yearbook Vestfoldminne from 1924 to 1932. He was a recipient of the Swedish Order of the Polar Star.
In 1901 Johnson married Anna Evie Tollefsen, the daughter of Even Tollefsen, the inventor of the tanker. They had four children, the youngest of whom was the historian Arne Odd Johnsen.
