Knud Plesner Ibsen (3 October 1797, in Skien – 24 October 1877, in Skien) was a Norwegian merchant from the city of Skien and the father of the playwright Henrik Ibsen. He is widely considered the model for many central characters in his son's plays, including Jon Gynt in Peer Gynt and Old Ekdahl in The Wild Duck. Through the Paus family—the family of Knud's stepfather Ole Paus and Marichen's mother Hedevig—Knud was raised as a close relative of his would-be wife Marichen Altenburg, although they were not closely related biologically.[1][2]
