1) Knut Hamsun was a Norwegian author who was awarded the Nobel Prize in Literature in 1920 for his novel Growth of the Soil. 2) He is best known for his 1890 psychological novel Hunger, which described a young writer's descent into madness due to poverty. 3) Hamsun strongly advocated for Nazi Germany before and during World War 2, sending his Nobel medal to Joseph Goebbels and praising Hitler, which tarnished his reputation. However, he is still considered "Norway's soul" and efforts to prosecute him for treason were dropped due to mental decline.
