John Henry O'Hara was one of America's most prolific writers of short stories, credited with helping to invent The New Yorker magazine short story style. He became a best-selling novelist before the age of 30 with Appointment in Samarra and BUtterfield 8. While O'Hara's legacy as a writer is debated, his work was praised by such contemporaries as Ernest Hemingway and F. Scott Fitzgerald, and his champions rank him highly among the major under-appreciated American writers of the 20th century. Few college students educated after O'Hara's death in 1970 have discovered him, chiefly because he refused to allow his work to be reprinted in anthologies used to teach literature at the college level.

A short story is a piece of prose fiction. It can typically be read in a single sitting and focuses on a self-contained incident or series of linked incidents, with the intent of evoking a single effect or mood. The short story is one of the oldest types of literature and has existed in the form of legends, mythic tales, folk tales, fairy tales, tall tales, fables and anecdotes in various ancient communities around the world. The modern short story developed in the early 19th century.
