During World War II a number of Norwegian Quakers, including Olden and Lund, were imprisoned by the occupying German forces for resistance work. Lund was active in the Norwegian underground movement protecting Norwegian Jews and refugees and in 1947 she became the first member of the Oslo Worship Group to become a Quaker. Olden was later nominated for the 1957 Nobel Peace Prize. Lindgrov School was established by Norwegian Friends in 1959, contributing ideas to national policies concerning training and work as aspects of care for people with learning disabilities. In 1975, a Monthly Meeting was established in Kristiansand.
