[2][3][4][5] Stephane Custot was born in Neuilly, Paris in 1963 (or 1962), the son of a society dentist and collector of Chinese art.

[citation needed] In 1984, he founded the Galerie Hopkins-Custot[7] with Waring Hopkins in Paris, Avenue Matignon.

While working at the gallery, in 1991, Custot joined forces with Patrick Perrin to create a new fair: the Salon du Dessin.

[8][9] In 1998, Emmanuel Moatti joined Custot and Perrin, and they opened the Salon des Beaux-Arts in Paris.

[16] The gallery is located at 11-12 Cork Street, Mayfair in London, and exhibits the work of British, European and American artists.

He developed the publishing side of the business, producing the first monographs on Barry Flanagan and Jedd Novatt.
