O. Henry

Henry, O. (William Sidney Porter; 1862–1910), U.S. short-story writer noted for the “surprise ending.” He began writing stories while imprisoned in Ohio for embezzlement, and was already popular when released. He moved to New York City in 1902 and wrote over 300 stories, collected in The Four Million (1906), The Voice of the City (1908), and many other books. His last years were marred by an unhappy marriage and financial difficulties.
