Bjørn Arnold Rørholt DSO (27 August 1919 – 3 May 1993) was a Norwegian engineer, military officer, Secret Intelligence Service agent and resistance member during World War II.
[1] Not long after, when the Norwegian Military Academy opened for an extra influx of recruits, Rørholt enrolled there.
[2] When World War II reached Norway on 9 April 1940, with the German invasion, the Military Academy cadet Rørholt helped fighting to repel the invaders.
[5] Rørholt fled to Sweden via Iddefjord, accompanied by Knut Haukelid who had been involved in the Skylark A group in Oslo.
[3] Rørholt held a false identity as an insurance agent, and was thus allowed to travel freely with the alleged purpose of visiting customers.
[9] From November 1942, Rørholt was transferred to the department 4 (FO IV) of the Ministry of Defence, chairing the education of Norwegian radio agents in Great Britain.
[7] From 1944 to 1945, he participated in the liberation of Northern Norway, being one of the key figures on the Norwegian side together with Bernt Balchen.
He had a position at the Norwegian Embassy in Washington DC, and later continued his engineering studies at the Harvard University, specializing in binary and communication technology.
[13] He wrote two memoir books from his World War II experiences, Amatørspionen "Lerken" ("Amateur Spy 'The Lark'", 1985) and Usynlige soldater ("Invisible Soldiers", 1990)—the latter together with Bjarne Thorsen.
