Josef Monsrud (29 May 1922, in Lunner, Oppland – 12 December 2009) was a Norwegian forester and resistance member during World War II.
He went through some initial training and performed sabotage missions in Hadeland before being hired as a guard in the Communist Party of Norway.
On 30 October 1942 the guard hut was attacked by German soldiers and Monsrud and fellow resistance fighter Finn Eriksen were captured.
[3] The Osvald Group later split with the Communist Party,[2] and Monsrud joined Milorg, working for the Secret Intelligence Service with the illegal radio transmitter Gullfaks.
[4] Named after Gullfaxi of Norse mythology, Gullfaks was operated from different places in Bærumsmarka and Nordmarka until the liberation of 8 May 1945.
