He received Hartvig Lassen's gold medal for his dissertation Henrik Wergeland og Henrich Steffens in 1919.^[2] He became dr.philos. in 1924, with the thesis Søren Kierkegaard og Norge. He was a teacher in secondary school for 34 years, in Haugesund from 1917 and later at Bergen Cathedral School from 1922, except for one year at the University of Hamburg from 1930 to 1931. During his period as a teacher, he was a literary critic for the newspaper Bergens Tidende, amassing about 1600 articles. Selections of his articles were issued in Fra Holberg til Hamsun.
