Einar Olav Dønnum (1897 – 22 April 1947) was a Norwegian Nazi collaborator who was executed during the legal purge in Norway after World War II.
During the occupation of Norway by Nazi Germany, he worked in the Nazi-dominated Statspolitiet. He was known for brutal interrogation methods, which included torture. He hired his teenage son as an assistant.[1]
Members of the Norwegian resistance movement, including Asbjørn Sunde, had several failed assassination attempts towards Dønnum. However, the Nazi occupation ended on 8 May 1945, and in 1947, as a part of the legal purge in Norway after World War II, his son was sentenced to six years of forced labour, and Einar Dønnum was sentenced to death for treason.[1] He was executed at Akershus Fortress on 22 April 1947.
