Charles-Edmond Duponchel (7 April 1804 – 13 February 1864) was a French military officer accountant, in which capacity he served in Spain and Algeria.
In 1823 he entered the École des Beaux-Arts, where he studied with the architects Pierre-Théodore Bienaimé (1765–1826) and Léon Vaudoyer (1803–1872).
In these he explained his reasoning and mentions that for practical advice he had gone to see "M. Duponchel [Henri Duponchel], former director of the Opera and certainly the man most competent at this juncture in matters concerning theatre construction, considering that he is at the same time a great administrator and a great artist".
[4] He also prepared documents dealing with the Algerian question and proposals for barracks to accommodate troops, which have also been misattributed to the director of the Opera.
He edited and wrote an introduction for the 12-volume Nouvelle bibliothèque des voyages anciens et modernes contenant la relation complète ou analysée des voyages de Christophe Colomb, Fernand Cortez,..., which was published in 1842.
