Charles Polycarpe Séchan (29 June 1803 – 14 September 1874) was a French painter and theatre designer.
Born in Paris, son of the tailor merchant Jean-Fris Séchan, he lost his parents, who had no fortune, very early on.
He made his first steps in the career by entering the studio of Lefèvre, decorator of the Théâtre de la Porte-Saint-Martin.
He created the sets of Périnet Leclerc, by Lockroy and Auguste Anicet-Bourgeois, and particularly the one representing a Vue du vieux Paris, was executed entirely on his drawings.
[1] Recommended by the marquis de la Valette, he was commissioned by the sultan Abdulmejid I to create the decoration of the new Dolmabahçe Palace.
