Louis Leonard De Lomenie, a French author, born at St. Yrieix, Haute-Vienne, in 1818. He is descended from the family of the cardinal Lomenie de Brienne, who was comptroller of finances in 1787 and prime minister for a few months in 1788, and died from the brutal treatment of the revolutionists in 1794. He early applied himself to literature in Paris, and published, under the pseudonyme of Un Homme de Rien, a series of political and literary biographies known as the Galerie des contem-porains illustres (10 vols. 18mo, Paris, 1840-'47). In 1845 he was selected as the substitute of J. J. Ampere in the chair of French literature at the college de France, and in 1864 became permanent professor, in which office he has since been succeeded by Guillaume Gui-zot; but he holds a professorship in the polytechnic school. Many years since he commenced the publication in different periodicals of another series of biographical sketches, Les hommes de '89, but their issue was suspended. His most valuable work is Beaumarchais et son temps, etudes sur la societe francaise (2 vols. 8vo, 1855; 2d ed., 1858). This was translated into English in 1857 (4 vols.), and abridged in New York. In January, 1874, he was elected a member of the French academy as successor of Prosper Merimee.
