O. Henry was a pen name used by an American writer of short stories. His real name was William Sydney Porter. He was born in North Carolina in 1862. As a young boy he lived an exciting life. He did not go to school for very long, but he managed to teach himself everything he needed to know. When he was about 20 years old, O. Henry went to Texas, where he tried different jobs. He first worked on a newspaper, and then had a job in a bank. When some money went missing from the bank, O. Henry was believed to have stolen it. Because of that, he was sent to prison. During the three years in prison, he learned to write short stories. After he got out of prison, he went to New York and continued writing.
