In 1874, the first exhibition of Impressionist paintings was held at 35 Boulevard des Capucines, in the former studio of the photographer Gasper-Félix Tournachon. Edgar Degas, Pierre-Auguste Renoir, Camille Pissarro, Alfred Sisley, Paul Cézanne, and, of course, Claude Monet were among the exhibitors. The movement took its name from one of Monet’s plein air landscape paintings—a striking work called Impressionism, Sunrise. Looking at the serene naturescapes today, audiences often forget that these pioneers were cast out from the mainstream art world, and treated as scandalous renegades. This exhibition, which celebrates Impresionism’s 150th anniversary, reflects on the revolutionary path these painters forged. —Elena Clavarino
