Shortly after the war, General Charles de Gaulle appointed Malraux as his Minister for Information (1945–1946). Soon after, he completed his first book on art, The Psychology of Art, published in three volumes (1947–1949). The work was subsequently revised and republished in one volume as The Voices of Silence (Les Voix du Silence), the first part of which has been published separately as The Museum without Walls. Other important works on the theory of art were to follow. These included the three-volume Metamorphosis of the Gods and Precarious Man and Literature, the latter published posthumously in 1977. In 1948, Malraux married a second time, to Marie-Madeleine Lioux, a concert Pianist and the widow of his half-brother, Roland Malraux. They separated in 1966. Subsequently, Malraux lived with Louise de Vilmorin in the Vilmorin family château at Verrières-le-Buisson, Essonne, a suburb southwest of Paris. Vilmorin was best known as a Writer of delicate but mordant tales, often set in aristocratic or artistic milieu. Her most famous novel was Madame de..., published in 1951, which was adapted into the celebrated film The Earrings of Madame de… (1953), directed by Max Ophüls and starring Charles Boyer, Danielle Darrieux and Vittorio De Sica. Vilmorin's other works included Juliette, La lettre dans un taxi, Les belles amours, Saintes-Unefois, and Intimités. Her letters to Jean Cocteau were published after the death of both correspondents. After Louise's death, Malraux spent his final years with her relative, Sophie de Vilmorin.
