Alexandre Louis Joseph Bertrand (11 June 1820 - 1902) was a French archaeologist born in Rennes.
He was the son of physician Alexandre Jacques François Bertrand (1795-1831) and elder brother to mathematician Joseph Louis François Bertrand (1822-1900).
Alexandre Bertrand studied at the École Normale Superieure, and later taught classes at the lycée in Laval (from 1848). In 1849 he became a member of the École française d'Athènes, and from 1851 to 1858, served as a professor of rhetoric at the lycée in Rennes.[1]
Bertrand was a pioneer of Gallic and Gallo-Roman archaeology, and was involved in the archaeological dig at Alise-Sainte-Reine (1861/62). In 1864, with Louis Félicien de Saulcy, he directed excavations of burial mounds at Meloisey.[1]
In 1862 he founded the Gallo-Roman museum in Saint-Germain-en-Laye, serving as its curator from 1867 until his death in 1902. Assisting him in this endeavor were Gabriel de Mortillet (1868 to 1885) and Salomon Reinach (1886 to 1902).[1]
From 1882 he taught classes in archaeology at the École du Louvre.[1] He was an editor of Revue Archeologique and a member of Académie des Inscriptions et Belles-Lettres.[2]
