Thierry, JACQUES NICOLAS AUGUSTIN (1795-1856), French historian, was born at Blois, and, after leaving college, became a teacher, which profession he abandoned to become a disciple and secretary of St. Simon (q.v.). His earliest work, an unimportant one, appeared in 1816, and he joined the ranks of journalism soon after. Scott's novels had aroused in him a great interest in history, which led to the publication of several valuable works, notably Histoire de la Conquete de l'Angleterre par les Normandes (1825), which has become a standard \work. The application necessary to complete this work cost him his eyesight. Among his other works may be mentioned the Dix Ans d'Etudes Historiques (1834) and Recits des Temps Merovingiens (1840).
