Jean-Baptiste Benoît Eyriès (ʒɑ̃ batist bənwa ɛːʁjɛs; 24 June 1767 13 June 1846) was a French geographer, author and translator, best remembered in the English speaking world for his translation of German ghost stories Fantasmagoriana, published anonymously in 1812, which inspired Mary Shelley and John William Polidori to write Frankenstein and The Vampyre respectively. He was one of the founding members of the Société de Géographie, a member of the Société Asiatique, Académie des Inscriptions et Belles-Lettres, American Philosophical Society, and American Academy of Arts and Sciences, and was awarded the Legion of Honour. He had a mountain named after him near Yos Sudarso Bay in New Guinea, as well as a sandbank near French Island, Australia, and a street in Le Havre. Born in Marseille on 24 June 1767, the son of Jacques-Joseph Eyriès, a "lieutenant de frégates du roi" ('lieutenant of the king's frigates'), and Jeanne-Françoise Deluy (1748–1826). He moved to Le Havre in 1772 when his father was promoted to "commandant de la Marine" ('commander of the Navy'), and went to study at the College of Juilly. Eyriès began to travel to England, Germany, Sweden and Denmark to learn their languages and study botany and mineralogy, and through it grew to love geography and travel. Returning to Le Havre, he began working in the armaments trade, including commercial expeditions to various parts of the world, while taking care of a natural history museum there. In 1794 he went to Paris to free his father, who had been detained as a suspect in the new Republic, moving there the following year to devote himself to his studies, where he attended lectures by Antoine Laurent de Jussieu and Georges Cuvier, and started collecting old travel books. He was given a mission in 1804–1805 by Charles Maurice de Talleyrand-Périgord and Napoleon to travel to Germany and rally the French emigrants there, chosen for his knowledge of the country and language and his discretion.
