Legacy

Thomas Mann described him as a "descendant of Fyodor Dostoyevsky and Friedrich Nietzsche." Arthur Koestler was a fan of his love stories. H. G. Wells praised Markens Grøde (1917) for which Hamsun was awarded the Nobel Prize in Literature. Isaac Bashevis Singer was a fan of his modern subjectivism, use of flashbacks, his use of fragmentation, and his lyricism. A character in Charles Bukowski 's book Women referred to him as the greatest writer who has ever lived.

A fifteen-volume edition of Hamsun's complete works was published in 1954. In 2009, to mark the 150th anniversary of his birth, a new 27-volume edition of his complete works was published, including short stories, poetry, plays, and articles not included in the 1954 edition. For this new edition, all of Hamsun's works underwent slight linguistic modifications in order to make them more accessible to contemporary Norwegian readers. Fresh English translations of two of his major works, Growth of the Soil and Pan, were published in 1998.

Hamsun's works remain popular. In 2009, a Norwegian biographer stated, "We can’t help loving him, though we have hated him all these years... That’s our Hamsun trauma. He’s a ghost that won’t stay in the grave."

Three of Hamsun's homes (Hamsund gård in Hamarøy Municipality, Hamsunstugu in Garmo in Lom Municipality, and Nørholm in Grimstad Municipality) are open to the public as museums, in addition to the Knut Hamsun Centre in Hamarøy.

The whereabouts of Hamsun's Nobel Prize medal remain unknown.
