Until his death in 2010, Breandán Ó Buachalla held the first Thomas and Kathleen O’Donnell Chair of Irish Language and Literature at the University of Notre Dame. In addition to his appointment as Burns Visiting Scholar and fellowships at Cambridge University and New York University, Ó Buachalla was a former Professor of Modern Irish at University College Dublin and Professor of Irish in the School of Celtic Studies at the Dublin Institute for Advanced Studies. A scholar of the literature and ideology of early-modern Ireland, he is noted for his analysis of the effect of the Counter-Reformation on Irish political thought, as well as his comprehensive study of Irish Jacobitism. Ó Buachalla also leaves a legacy in linguistics, having published widely in that field as well.
