Máirtín Ó Cadhain (1906–1970), a language activist, is generally acknowledged as the doyen (and most difficult) of modern writers in Irish, and has been compared to James Joyce. He produced short stories, two novels and some journalism. Máirtín Ó Direáin (1910–1988), Máire Mhac an tSaoi (b. 1922) and Seán Ó Ríordáin (1916–1977) were three of the finest poets of that generation. Eoghan Ó Tuairisc (1919–1982), who wrote both in Irish and English, was noted for his readiness to experiment in both prose and verse. Flann O'Brien (1911–66), from Northern Ireland, published an Irish language novel "An Béal Bocht" under the name Myles na gCopaleen.
