Ernesto Sábato, born in 1911 in Rojas (province of Buenos Aires), joined the Communist Party when he was a student in La Plata, and then left the party before the war. In 1938, he got a Doctorate degree in Physics and a scholarship at Curie Institute in Paris. In the French capital city he knew the surrealist movement (Oscar Domínguez, Wilfredo Lam, Tristán Tzara, André Bretón), which would have a great influence in the writer’s work.
He divided his life between the atom research during the day and Montparnasse bohemian life at night. After a year at MIT in the United States he came back to Buenos Aires in 1940 and decided to abandon his scientific career to be devoted to literature and painting.
