Gustave Xavier Delacroix De Ravignan, a French preacher, born in Bayonne, Dec. 2, 1795, died in Paris, Feb. 26, 1858. He studied law, and in 1821 became counsellor to the royal court of Paris, and deputy attorney general near the tribunal of the Seine. He resigned and entered the Jesuit novitiate at Montrouge in 1822, was ordained priest in 1828, and taught theology at St. Acheul till 1830, and afterward at Brig in the Valais till 1833. His Lenten sermon in the cathedral of Amiens in 1831 laid the foundation of his fame as a preacher. In 1836 he preached a Lenten sermon in Paris, and shortly after succeeded Lacordaire in the pulpit of Notre Dame, which he occupied till 1848. In 1844 the attacks made on the Jesuits in the public press and the legislature induced him to publish an apologetic work entitled Be l'exis-tence et de l'institut des Jésuites (7th ed., 1855). In 1837 he founded a house of his order in Bordeaux, which he governed for four years; and in 1848 he became superior of the Parisian residence in the rue de Sèvres, the interval being filled up by charity sermons, and the foundation and direction of various charitable and pious associations, all aiming at the improvement of the common people. In 1851 he visited London during the universal exhibition, and gave a course of lectures.

In 1852 he wrote at the instigation of Pius IX. his Clement XIII. et Clément XIV., a history of the suppression of the Jesuits, designed to counteract the extreme views of Theiner and Crétineau-Joly. His life was written by Poujoulat (1858) and by Père de Ponlevoy (2 vols., 1860; English translation, New York, 1873).
