Ib Henriksen

Ib Henriksen is one of the few pseudonyms used by Norwegian author and philosopher Peter Wessel Zapffe (1899-1990). It was used when he published his Ibsen-travesty Hos doktor Wangel (en. With dr. Wangel) in 1974. The pseudonym is an anagram based on the name of a Norwegian playwriter, Henrik Ibsen (1828-1906).
