During the German occupation of Norway he was a member of the Norwegian resistance movement. He was arrested in January 1944, and spent time at the concentration camps Grini, Natzweiler, Dachau, Ottobrunn, Dautmergen and Vaihingen.[1] In April 1945 sixteen Norwegians were liberated by the White Buses from Vaihingen, among them Grindrud and later Prime Minister Trygve Bratteli.[2]
Grindrud served as a deputy representative to the Norwegian Parliament from the Market towns of Buskerud county during the term 1945 - 1949.
