DUILHÉ de SAINT-PROJET, MARC-ANTOINE-FRANÇOIS. - Noted French preacher and apologist, b. at Toulouse on 15 July 1822, d. there on 15 May 1897. Ordained priest in 1846, he taught literature and philosophy for several years at the seminary of Esquile.
In 1857 he received a doctorate in theology at the Sorbonne. His doctoral dissertation, Des études religieuses en France depuis le XVIIe siècle jusqu'à nos jours, ou Essai sur les causes qui ont produit dans les temps modernes la splendeur et la décadence des sciences théologiques, was published in Paris in 1861. In that same year D. began publishing his Revue de l'année religieuse, politique, philosophique et littéraire, issued until 1866. Having abandoned teaching, he devoted himself to preaching (1858), in which he achieved excellent success. Noteworthy were his Apologetic Conferences on faith and science (1869 and 1870). In 1875 he was appointed secretary general of the organizing committee of the Catholic University of Toulouse. Two years later (1877) he began his Apologetic Courses in the Faculty of Theology; in 1879 he became dean of the Faculty of Philosophy, and in 1894 rector of the Institute. His activity was also manifested in his initiative in promoting the International Congresses of Catholic Scientists.
His principal work, Apologie scientifique de la foi chrétienne, published at Toulouse in 1885, went through several editions and translations.
