KATSCHTHALER, JOHANNES. - Theologian and cardinal, born on 29 May 1832 at Hippach (diocese of Brixen), died at Salzburg on 27 February 1914. After graduating in theology at the faculty attached to the Seminary, he held the chair of dogmatic theology there until 1874, when he moved to the University of Innsbruck as professor of the history of dogma and apologetics.
In 1880 he was appointed canon of the metropolitan church of Salzburg and shortly afterwards rector of the Seminary. In 1891 he was chosen by Cardinal Haller as coadjutor and was consecrated titular bishop of Cibyra. He succeeded to the see of Salzburg in 1900 and received the red hat in 1903.
A man of wide culture and remarkable scientific and pastoral activity, he left many writings of a theological, apologetic, oratorical and musical nature. His fame rests chiefly on his *Theologia dogmatica catholica specialis* (5 vols., Regensburg 1877-88), in which orthodoxy of doctrine is combined with abundant erudition and clarity of style. His *Geschichte der Kirchenmusik* (pt. 1, 1893; Italian trans. by P. Guerrini, Turin 1926), written in the form of articles while he was editor of the *Kirchenmusikalische Vierteljahrsschrift*, is highly esteemed and widely circulated.
