As one of the founding figures of Impressionism, Camille Pissarro exerted considerable influence over the movement’s other members, such as Paul Ce´zanne, Claude Monet, Paul Gauguin, Edgar Degas, and Mary Cassatt. This publication focuses on Pissarro’s collaborations with these and other artists. It also celebrates the avant-garde quality of his painting, particularly in his contributions to Neo-Impressionism.
