Brian Ó Cuív
Ó Cuív was professor of Celtic Studies at University College Dublin and later at the Dublin Institute for Advanced Studies.[2] His later years were devoted to the compilation of a catalogue of the Irish manuscripts in the University of Oxford.[4] Their son — Éamon Ó Cuív — is a prominent Irish politician.[2] Ó Cuív's surname was changed from Ó Caoimh (O'Keeffe) by his father, Shán Ó Cuív, a Cork journalist, who in the early 20th century changed the spelling of his surname to conform with a simplified spelling system of his own invention, which he called An Leitriú Shimplí.[5] The letter 'v' is extremely rare in Irish outside modern loanwords.
