André Malraux, the French novelist, minister of cultural affairs, and art theorist, published his seminal book "Le Musée imaginaire" in the early 1950s. In "The Book on the Floor: André Malraux and the Imaginary Museum," art historian Walter Grasskamp takes Malraux’s work as a launching point to explore Malraux and his contemporary André Vigneau, the early history of the illustrated art book, and how Malraux’s vision for a “museum without walls” anticipated a new approach to art history that was comparative and global in scope. Thomas Gaehtgens, director of the Getty Research Institute, joins the conversation.
