Ernest Miller Hemingway (July 21, 1899 – July 2, 1961) was an American journalist, novelist, short-story writer, and sportsman. His economical and understated style—which he termed the iceberg theory—had a strong influence on 20th-century fiction, while his adventurous lifestyle and his public image brought him admiration from later generations. Hemingway produced most of his work between the mid-1920s and the mid-1950s, and he won the Nobel Prize in Literature in 1954. He published seven novels, six short-story collections, and two non-fiction works. Three of his novels, four short-story collections, and three non-fiction works were published posthumously. Many of his works are considered classics of American literature.
