Drawing on unpublished letters and other documents, a leading French historian/biographer traces the life and times of art dealer Durand-Ruel (1831-1921). Ruel supported the careers of most of the major Impressionist artists including Degas, Manet, Monet, Morisot, Pissarro, Renoir, and Sisley. Photos feature the artists and art championed by Ruel.
