O. Henry, born William Sydney Porter (1862-1910), was an American short-story writer famed for his clever plots and unexpected twists. Originating from Greensboro, North Carolina, he held various jobs, such as a pharmacist, draftsman, and bank teller. Among his most celebrated works are "The Gift of the Magi" and "The Ransom of Red Chief." His stories often romanticized the daily lives of ordinary people in New York City. Interestingly, Porter adopted the pen name O. Henry while serving a prison sentence for embezzlement, during which he penned many of his well-known tales. Porter also wrote poetry and non-fiction. Porter's legacy includes the O. Henry Award, an annual prize awarded to outstanding short stories.
