DARMESTETER, ARSENE (1846-1888), elder brother of James Darmesteter (see below), was a distinguished philologist and man of letters. He studied under Gaston Paris at the Ecole des Hautes Etudes, and became professor of Old French language and literature at the Sorbonne. He collaborated with Adolphe Hatzfeld in a Dictionnaire general de la langue francaise (2 vols., 1895-19oo). Among his most important work was the elucidation of Old French by means of the many glosses in the mediaeval writings of Rashi and other French Jews. His scattered papers on romance and Jewish philology were collected by James Darme steter as Arsene Darmesteter, reliques scientifiques (2 vols., 189o). His Cours de grammaire historique de la langue francaise was edited after his death by E. Muret and L. Sudre (1891-95, English edition, 1902).
