Thurneysen, Rudolf (1857-1940), scholar. Born in Basle, Switzerland, he taught at the Universities of Jena, 1885-7, Freiburg, 1887-1913, and Bonn, where he trained many leading Celtic scholars who were to be associated with the DIAS, among them Osborn Bergin, D. A. Binchy, Myles Dillon, and James Carney. He was a pioneer in the application of historical and comparative linguistics to Old Irish. His Handbuch des Altirischen (2 vols., 1909) described the grammatical structure of Old Irish and was translated by Bergin and Binchy as A Grammar of Old Irish (1946). Other major works include Die irische Helden- und Königsage (The Irish Sagas of Heroes and Kings) (1912), a study of the Ulster and historical cycles of tales.
