Brian O'Nolan Brian O'Nolan (Irish: "Brian Ó Nualláin" ; 5 October 1911 – 1 April 1966) was an Irish novelist, playwright and satirist, considered a major figure in twentieth century Irish literature. 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 Bocht" were written under the name Myles na gCopaleen.
Amanda McKittrick Ros Anna Margaret Ross (née McKittrick; 8 December 1860 – 2 February 1939), known by her pen-name Amanda McKittrick Ros, was an Irish writer. She published her first novel "Irene Iddesleigh" at her own expense in 1897. She wrote poetry and a number of novels. Her works were not read widely, and her eccentric, over-written, "purple" circumlocutory writing is alleged by some critics to be some of the worst prose and poetry ever written.
