A 20th-century Irish author of short fiction, he is best known for "The Man of the House" and other autobiographical stories. The Frank O'Connor International Short Story Award was named in his honor.
He served in the Irish Republican Army during the Irish War of Independence. Later, he worked as the managing Director of the famous Abbey Theatre in Dublin.
His wartime experiences factored into his decision to publish "The Big Fellow," a biography of an Irish Independence leader.
His father was an alcoholic, so his mother took care of him and his siblings and provided most of the family's income. O'Connor was married twice--to Evelyn Bowen and Harriet Rich-- and fathered four children.
