Benito Pérez Galdós (1843–1920) is considered the greatest Spanish writer after Cervantes. In a career that spanned more than forty years, Galdós wrote nearly eighty novels and some twenty plays. Tristana, also available as an NYRB Classic, and other books of his were adapted for the screen by the great surrealist filmmaker Luis Buñuel.
