“ LA VILLEMARQUÉ, THÉODORE CLAUDE HENRI, Vicomte Hersart de (1815–1895) , French philologist and man of letters, was born at Keransker, near Quimperlé, on the 6th of July 1815. He was descended from an old Breton family, which counted among its members a Hersart who had followed Saint Louis to the Crusade, and another who was a companion in arms of Du Guesclin. La Villemarqué devoted himself to the elucidation of the monuments of Breton literature. Introduced in 1851 by Jacob Grimm as correspondent to the Academy of Berlin, he became in 1858 a member of the Academy of Inscriptions. ”
