BERTHIER, JOACHIM. — Born on 31 December 1848 at Talloires near Annecy (Savoy), died on 21 December 1924 at Fribourg (Switzerland). Educated at the college of La Roche, after discovering his priestly vocation he first entered the seminary of Annecy and then that of Fribourg, in order to enter the Order of Preachers on 13 February 1872; ordained a priest in 1874 in the cathedral of Avignon, he was lecturer in theology and ecclesiastical history at the college of Carpentras. Called to Rome in 1880, he collaborated on the complete and critical edition of the scientific works of s. Thomas Aquinas and, having settled at S. Sabina, made it the center of his spiritual and intellectual work. The author of numerous theological, historical, and literary writings, he later went to Fiesole and Florence, from where he returned to Fribourg, where he remained from 1890 to 1905 and was one of the founders of that Catholic University.
He returned to S. Sabina in 1906, of which he became, as Pope Pius XI expressed it in announcing his death, « its guardian genius », and he was not content until he had obtained, in 1914, the beginning of restoration work and the reinstatement of the ancient title and adjoining Dominican convent; after the basilica was reopened to the public in June 1919, he departed again for Fribourg, where he died.
His principal works are: Summa de donis s. Joseph, auctore fr. Isidoro denuo edita (Rome 1887); B. Humberti de Romanis Quinti Praedicatorum Magistri Generalis opera de Vita Regulari (there 1888, 2 vols.); Vita di Papa Innocenzo XI (there 1889); Mystica Theologia Divi Thomae (Turin 1890); B.
