Hemingway had a strong influence on 20th-century fiction, while his life of adventure and his public image influenced later generations. Hemingway produced most of his work between the mid-1920s and the mid-1950s, and won the Nobel Prize in Literature in 1954. He published seven novels, six short story collections, and two non-fiction works. Additional works, including three novels, four short story collections, and three non-fiction works, were published posthumously. Many of his works are considered classics of American literature.
