Laura Gascoigne reviews Camille Pissarro: The First of the Impressionists at the Musée Marmottan Monet, Paris, until July 2, 2017.

Gascoigne begins: “If asked to name the key figure in Impressionism, few people today would nominate Camille Pissarro… Yet to his contemporaries this quiet revolutionary was the unifying force behind the movement that he had helped to launch with the first Impressionist exhibition in 1874; he was the only member of the group to show in all eight Impressionist exhibitions. ‘We learned everything we do from Pissarro,’ said Paul Cézanne in the 1890s. ‘It’s he who was really the first Impressionist.’”
