Adolfo Bioy Casares (1914-1999) began to write in the early 1930s, and his stories appeared in the influential magazine Sur, through which he met his wife, the painter and writer Silvina Ocampo, as well Jorge Luis Borges, who was to become his mentor, friend, and collaborator. In 1940, Bioy published the novella The Invention of Morel, the first of his books to satisfy him. Later publications include stories and novels, among them A Plan for Escape, A Dream of Heroes, and Asleep in the Sun.
