A new exhibition entitled Henri Cartier-Bresson: The Decisive Moment examines Magnum co-founder Henri Cartier-Bresson’s influential publication, widely considered to be one of the most important photobooks of the twentieth century. Pioneering for its emphasis on the photograph itself as a unique narrative form, The Decisive Moment was described by fellow co-founder Robert Capa as “a Bible for photographers.”

The exhibition details how the decisions made by the collaborators in this major project—including Cartier-Bresson, French art publisher Tériade, American publisher Simon & Schuster, and Henri Matisse, who designed the book’s cover—have shaped our understanding of Cartier-Bresson’s photographs and directly influenced the medium.

Through vintage gelatin silver prints, first-edition publications, periodicals, and correspondence, Henri Cartier-Bresson: The Decisive Moment brings new insights to his iconic work.
