Gunnar Sønsteby was a member of the Norwegian resistance during World War II, and is also known for being the most highly decorated person in Norway.

After the German occupation of Norway Sønsteby, known as Kjakan (The Chin) and No. 24, among other aliases, became active in the Norwegian resistance. He later became agent 24 of the Special Operations Executive, a UK based organization, and was contact for all SOE agents in Norway as well as head of Norwegian Independent Company 1. The company performed several amazing and infamous acts of sabotage. To avoid capture by the Gestapo, he operated under thirty to forty different names, and was never captured. Sønsteby is still alive today, at the age of 93.

For his efforts, Sønsteby was awarded ten medals, five of which are Norwegian. He is also the only person to have been awarded the War Cross with Three Swords.
