Born Halldór Guðjónsson, he adopted the surname Laxness in honour of Laxnes in Mosfellssveit where he grew up, his family having moved from Reyjavík in 1905. He published his first novel at the age of only 17, the beginning of a long literary career of more than 60 books, including novels, short stories, poetry, and plays. Confirmed a Catholic in 1923, he later moved away from religion and for a long time was sympathetic to Communist politics, which is evident in his novels World Light and Independent People. In 1955 he was awarded the Nobel Prize for Literature.
