Ole Hallesby Writer
Ole Kristian Hallesby (5 August 1879 – 22 November 1961) was an influential conservative Norwegian Lutheran pietist who taught at the Free Faculty of Theology from 1909 to 1952.An outspoken opponent of the Nazi occupation of Norway, he was arrested and detained at Grini concentration camp for two years (until the end of the war).During a razzia in November 1948 it was revealed that the already-imprisoned Nazi agents, Gard Holtskog, Sten Blom Westberg and Hans Johann Krijom, were about to fabricate a document which probably was supposed to tie Hallesby to the Nazis.Hallesby wrote 67 books, mostly on theology and ethics, but is known for devotional writings.
