After studying at
Heidelberg,
Bonn and
Berlin, he graduated at
Kiel in 1847, and the next year went to France, where he was a teacher of German at Laval and at Reims. His leisure was given to
Oriental studies, in which he had made great progress in Germany. In 1851 he joined the French archaeological mission to
Mesopotamia and
Media under
Fulgence Fresnel. On his return in 1854, he was naturalized as a French citizen in recognition of his services. He occupied himself with analyzing the results of the expedition, with special attention to the
cuneiform inscriptions he had collected. His account of the Fresnel mission and the results of his consequent study were published as
Expédition Scientifique en Mésopotamie (1859–1863), with the second volume entitled
Déchiffrement des inscriptions cunéiformes. The work was especially notable as most of the mission's excavations were lost in the
Al Qurnah disaster. Although the classification of the "Casdo-Scythian" inscriptions as Turanian would later be rejected by scholars, research would confirm Oppert in his identification of the distinctness of the
Sumerian language (as he renamed it in 1869) and the origin of its script. In 1856 he published
Chronologie des Assyriens et des Babyloniens. In 1857 he was appointed professor of
Sanskrit and comparative
philology in the school of languages connected with the
National Library of France, and in this capacity he produced his
Grammaire Sanscrite (1859). But his attention was chiefly given to
Assyrian and cognate subjects. He died in Paris on 21 August 1905. ==Bibliography==
