Michèle Aittouarès founded the Galerie Berthet-Aittouarès in 1986. In 2000 she was joined by her daughter Odile Aittouarès, art historian and author of the catalogue raisonné of Friesz, co-founder of the St. John's Photo Festival. Germain and the Association JeudiDesBeauxArts.

Their collaboration began with the exhibition "China-West or the Adventure of the Sign" around Zao Wou-ki, Mark Tobey, Jean Degottex, Henri Michaux and Shan Sa.
The gallery occupies two spaces on the left bank; initially at 29 rue de Seine, then at 2 rue des Beaux-arts, the former gallery of
