Charles le Beau, French historian and author (d. 1778)
Charles le Beau (18 October 1701, Paris – 13 March 1778, Paris) was a French historical writer.

He was born in Paris, and was educated at the Collège de Sainte-Barbe and the Collège du Plessis; at the latter he remained as a teacher until he obtained the chair of rhetoric in the Collège des Grassins. In 1748 he was admitted as a member of the Academy of Inscriptions, and in 1752 he was nominated professor of Latin eloquence at the Collège de France. From 1755 onward, he held the office of perpetual secretary to the Academy of Inscriptions, in which capacity he edited fifteen volumes (from the 25th to the 39th inclusive) of the Histoire of that institution.He is best remembered as the author of Histoire du Bas-Empire, en commençant à Constantin le Grand, in 22 volumes (Paris, 1756–1779). This is a continuation of Charles Rollin's Histoire Romaine and JBL Crevier's Histoire des empereurs. Its usefulness arises entirely from the fact of its being a faithful resume of the Byzantine historians. Five volumes were added by H.-P. Ameilhon (1781–1811), which brought the work down to the fall of Constantinople. A later edition was produced by Antoine-Jean Saint-Martin and afterwards of Marie-Félicité Brosset.
