He was born in Oslo as the son of Harald and Helga Marie Hansen. He worked in Oslo as an electrician. When Norway was invaded by Germany in 1940, he became involved in the subsequent fighting. He later involved himself in the illegal press, and later in Milorg. He conducted several sabotage missions as a part of the group D.B. He was also a part of the group Aks 13000. His last mission was "Aksjon smør", in which Milorg men stole foodstuffs from two warehouses, one in the street "Tollbugata" belonging to German forces, and one in the street "Skippergata" belonging to Arbeidstjenesten. The foodstuffs were distributed to Milorg men who hid in the forests surrounding Oslo. This was his 28th sabotage mission.
