About Julio Cortázar
Julio Florencio Cortázar was an Argentine and naturalised French novelist, short story writer, poet, essayist, and translator. Known as one of the founders of the Latin American Boom, Cortázar influenced an entire generation of Spanish-speaking readers and writers in America and Europe. His first printed book was a collection of sonnets heavily influenced by Stéphane Mallarmé called Presencia ("Presence"), published under the pseudonym Julio Denis in 1938. His first major work to be published under his real name was Los Reyes (1949, "The Monarchs"), a poetic drama that passed almost unnoticed.
