Louis Veuillot, a French author, born at Boynes, department of Loiret, in 1813. He is the son of a poor cooper, obtained a place in an attorney's office in Paris, and at the age of 19 his articles in the Echo de la Seine-Inférieure involved him in two duels. At the end of 1832 he became the editor-in-chief of the Memorial de la Dordogne, at Périgueux. In 1837 he went to Paris as editor of the Charte de 1830, founded by the ministry; and when that journal failed, he became principal editor of the Paix. Hitherto he had been distinguished for boldness and skepticism; but having in 1838 visited Rome during Holy "Week, he returned to France a zealous Catholic. In 1842 he went to Algeria as secretary of Gen. Bugeaud, and on his return became chief clerk in the ministry of the interior. In 1848 he became editor-in-chief of the Univers, on which he had been employed several years. While advocating extreme ultramontane views, he sided with the abbé Gaume in denouncing the use of the pagan classics in the Jesuit and other colleges and with Padre Ventura in combating the Jesuit philosophy as too rationalistic. His journal was interdicted in many dioceses, and in 1853 the bishop of Orleans expressly forbade his clergy to read it.

In 1860 it was suppressed by the emperor, but was allowed to reappear in 1867 with Veuillot as chief editor. During the discussions which preceded the council of the Vatican, the Univers was the foremost organ of the infallibilists. Veuillot resided at Rome during the council as the chief correspondent of his paper. He has written numerous works, relating principally to the tenets of the Roman Catholic church, and often bitterly attacking everything that came in conflict with what he conceived to be ultramontane doctrines and interests. His latest work is La vie de Jesus- Christ.
