in Discrepantia mss. et editionum (Helmstadt, 1715), 9-11. When in 1382 the French court compelled the professors of the College of Sorbonne (University of Paris) to acknowledge the antipope Clement VII, Henry left the university and spent some time at Eberbach Abbey, a Cistercian monastery near Wiesbaden. A letter which he wrote here to Bishop Eckard of Worms, and which bears the title De scismate was edited by Sommerfeldt in Historisches Jahrbuch (Munich, 1909), XXX, 46–61. Another letter which he wrote here to the same bishop, on the occasion of the death of the bishop's brother, is entitled De contemptu mundi (edited by Sommerfeldt in Zeitschrift für kath. Theologie (Innsbruck, 1905), XXIX, 406-412). A second letter of condolence, written about 1384, was edited by Sommerfeldt in "Hist. Jahrbuch" (Munich, 1909), XXX, 298–307. Following the invitation of Albert III, Duke of Austria, he went to the University of Vienna in 1384, and assisted in the foundation of a theological faculty. Here he spent the remainder of his life, teaching dogmatic theology, exegesis, and Canon law, and writing numerous treatises. In 1384 Heinrich von Langenstein, together with his colleague and friend Heinrich Totting von Oytha (who descended from the Northern German town now known as Friesoythe), took up teaching and administrative duties at the newly established University of Vienna (founded 1365, first students subscribed 1385). He died at Vienna, having refused an episcopal see which was offered him by Urban VI. Legacy In 2008 the University of Vienna attached a third memorial plaque to Heinrich von Langenstein and Heinrich Totting in the University Church, St. Stephen's Cathedral, Vienna (first: 1397 upon their burial in the Apostelchoir, second: upon re-burial of the two friends in the Katharinenkapelle 1510) near the Apostelchoir, acknowledging the two teachers the "founding professors" of the University of Vienna. Works Roth (see below) ascribes to him seven works on astronomy, eighteen historico-political treatises on the schism, seventeen polemics, fifty ascetical treatises, and twelve epistles, sermons and pamphlets. Among his printed works are: Tractatulus de arte praedicandi valde utilis, 1494 De conceptione, a defence of the Immaculate Conception (Strasburg, 1500) Contra disceptationes et praedicationes contrarias fratrum Mendicantium, another defence of the Immaculate Conception against some of the Mendicants (Milan, 1480; Basle, 1500; Strasburg, 1516) Speculum animae or mirror of the soul, an ascetic treatise edited by Wimpfeling (Strasburg, 1507) Secreta sacerdotum que in missa teneri debent multum utilia, treating of
