Otto Øgrim

He then moved to Oslo to work with advertising and study for the examen artium, which he completed as a private candidate in 1934.

[1] During the Second World War, Øgrim together with Arvid Storsveen was central in establishing the secret intelligence organization XU, from its start in the summer of 1940.

After Storsveen had to flee to Sweden in 1942 and was shot and killed by the Gestapo in 1943, Øgrim continued as a central XU operative in southern Norway under Øistein Strømnæs and Anne-Sofie Østvedt.

For more than 35 years, Øgrim worked as a lecturer at the Institute of Physics and a prolific textbook author at the University of Oslo.

The two won the Cappelen Prize in 1983,[2] for work on a widely used series of textbooks at high school level.
