Louis Charles André Alexandre Du Mège or Dumège, (The Hague (Netherlands) 5 December 1780 – Toulouse 6 June 1862), was a French scholar, archaeologist and historian.

In 1814, the mayor of Toulouse entrusted him with the defense of the city based on instructions from Marshal Jean-de-Dieu Soult, but the army's corps of engineers did not approve his plan, a rejection for which he long held a grudge.

[2] He brought a number of medieval works into the museum, specifically from the cloister of Notre-Dame de la Daurade and the portal of the chapter house of Saint-Étienne.

[6] In spite of the faults that can be attributed to him,[7] especially his lack of scientific rigor, he remains one of the main founders of the archeology of southern France, a character halfway between science and myth, uniting erudition and imagination, fiction and reality.

A marble bas-relief of the two emperors was discovered in 1832 in Nérac, department of Lot-et-Garonne in a Gallo-Roman villa in the area known as La Garenne, which was excavated under the direction of sculptor and forger Maximilien Théodore Chrétin [fr].
