Knut Hamsun (1859-1952) was a Norwegian writer and Nobel Prize in Literature laureate. His extensive literary career of over 70 years included the publication of more than 23 novels, poetry, short stories, plays, non-fiction, and essays. Hamsun's influence on literature is vast, pioneering psychological literature with techniques like stream of consciousness and interior monologue, which inspired prominent authors such as Thomas Mann, Franz Kafka, and Ernest Hemingway.
