Flann O'Brien is a pseudonym for Brian O'Nolan (1911-1966), an Irish novelist, playwright, and satirist. Born in Strabane, County Tyrone, he is regarded as a key figure in postmodern literature. His English language novels, such as At Swim-Two-Birds and The Third Policeman, were written under the pen name Flann O'Brien. His many satirical columns in the Irish Times and an Irish language novel An Béal Bochtwere written under the name Myles na gCopaleen. O'Nolan's novels have attracted a wide following for their bizarre humor and modernist metafiction.
