Seán O'Casey born John Casey (30 March 1880 – 18 Sep 1964) was an Irish dramatist and memoirist. A committed socialist, he was the first Irish playwright of note to write about the Dublin working classes. O'Casey's first accepted play, The Shadow of a Gunman, was performed at the Abbey Theatre in 1923. It was followed by Juno and the Paycock (1924) and The Plough and the Stars (1926). Juno and the Paycock became a film directed by The Plough and the Stars was not well received by the Abbey audience and resulted in scenes of a riot reported on the fourth night of the show. His depiction of sex and religion even offended some of the actors, who refused to speak their lines. In 1952 he appeared in a play by Irish playwright Teresa Deevy called "The Wild Goose" in which he played the part of Father Ryan. O'Casey was involved in numerous productions with the Abbey; these can be found in the Abbey Archives. Less
