Alexandre the son of a seller of artist's supplies in Besançon, and associated there with Courbet, with whose advice he set up a shop in Paris. Opening his shop in 1863 on the rue Lafitte, Bernheim became a merchant of paintings as well, and was introduced into Parisien high society. Alexandre's sons Gaston and Josse [1870-1941] continued the business, which then became known as Bernheim-Jeune. By the end of the nineteenth century they began to emphasize the exhibition and sale of impressionist paintings, editing a number of monographs on impressionist artists as well. Bernheim-Jeune, with its director of twenty years Félix Fénéon, was one of the most important commercial vehicles of the impressionists, after the galleries Durand-Ruel and Georges Petit.
