“Amitiés, Bonnard–Matisse,” now at the Fondation Maeght, consists of more than 300 loans that help illuminate the long friendship between Aimé Maeght, Pierre Bonnard, and Henri Matisse. A scholarly deep dive into the work of Bonnard and Matisse, their friendship, and their response to painting in the South of France, the exhibition also sheds light on Maeght’s first commercial venture as an art dealer, Galerie Maeght, opened during the Second World War. The Fondation was created by Maeght and his wife, Marguerite, in 1964. Heartbroken by the loss of their son Bernard, who was 11 when he died of leukemia, they threw themselves into the project with the help of artist friends Joan Miró, Marc Chagall, Georges Braque, and the Giacometti brothers. It has become a place of pilgrimage and an inspiration for art lovers, who return often to marvel at the now priceless foundation and Aimé Maeght’s genius in making it happen. —Sarah Hyde
