Hubert-Pascal Ameilhon (born in Paris, 7 April 1730; died 1811) was a French historian and librarian.
He first worked at the Bibliothèque historique de la ville de Paris, the city of Paris historical library. In 1766 he published a history of trade and seafaring in Ptolemaic Egypt, a work that was commended by the Académie des Inscriptions et Belles-Lettres;[1] he became a member of the academy in 1766.[2] He completed the multi-volume Histoire du Bas-Empire, a history of the Later Roman Empire and early medieval Europe, left unfinished by Charles Le Beau.[3] Taking up the work of Gabriel de La Porte du Theil he produced the first published translation (into Latin and French) of the Greek inscription on the Rosetta Stone: this was published in 1803.[4]
He was responsible for saving up to 800,000 printed books threatened with destruction in the early years of the French Revolution.[5] Many of these found a home at the Bibliothèque de l'Arsenal, of which he became director in 1800 (perpetual administrator in 1804).[2]
