William Golding switched his college major from science to English literature after two years, marking a change from his father's rationalism. His experience in World War II, where he served in the Navy and witnessed violence and the human condition, most influenced his writing of Lord of the Flies. After the war, Golding returned to teaching but wrote three rejected novels before getting the idea for Lord of the Flies from a conversation with his wife about letting characters "behave as they really would" in a children's story. Lord of the Flies made him famous, though he continued writing and experienced periods of both fame and obscurity over his career until winning the Nobel Prize in Literature in 1983.
