Henri-Marie Beyle , better known by his pen name Stendhal , was a 19th-century French writer. Known for his acute analysis of his characters' psychology, he is considered one of the earliest and foremost practitioners of realism in his two novelsLe Rouge et le Noir (The Red and the Black, 1830) andLa Chartreuse de Parme (The Charterhouse of Parma, 1839).
