FAIN, AGATHON JEAN FRANcOIS French historian, was born in Paris. Under the Consulate he en tered the office of the secretary of State, in the department of the archives. In 1806 he was appointed secretary and archivist to the cabinet particulier of the emperor, whom he attended on his cam paigns and journeys. He was created a baron of the empire in 1809, and, on the fall of Napoleon, was first secretary of the cabi net and confidential secretary. He published successively Manu scrit de 1814, contenant l'histoire des six derniers mois du regne de Napoleon (1823 ; new ed. with illustrations, 1906) ; Manuscrit de 1813, contenant le precis des evenements de cette annee pour servir d l'histoire de l'ernpereur Napoleon (1824) ; Manuscrit de 1812 (18 2 7) ; and Manuscrit de l'an iii. , contenant les premieres transactions de l'Europe avec la republique f rancaise et le tableau des derniers evenements du regime conventionnel (1828), which form a very valuable source for the history of Napoleon I. Of still greater importance for the history of Napo leon are Fain's Memoires, which were published posthumously in 1908. Immediately after the overthrow of Charles X., King Louis Philippe appointed Fain first secretary of his cabinet (Aug. 183o). Fain was a member of the council of State and deputy from Mon targis from 1834 until his death in Paris on Sept. 16, 183 7.
