Gertrude Stein's Masterpieces

Bathers, Paul Cézanne, 1898–1900
Before Leo Stein moved on to Matisse and Picasso, his collecting focused on artists of an earlier generation, including Manet, Renoir and Cézanne. Along with Degas, those were, for him, "the Big Four." Cézanne, he said, "has succeeded in rendering mass with a vital intensity that is unparalleled in the whole history of painting ... There can scarcely be such a thing as a completed Cézanne. Every canvas is a battlefield, and victory an unattainable ideal."
