Marie-Henri Beyle, writing under the pen name Stendhal, was a nineteenth-century French author widely regarded as one of the earliest and most prominent practitioners of literary realism. Born in 1783, Stendhal distinguished himself through his highly analytical approach to character psychology, a quality that led later commentators to describe him as a first-rate psychologist operating long before the formal discipline was established.\n\nHis literary reputation rests primarily on his masterpiece novels, Le Rouge et le Noir (1830) and La Chartreuse de Parme (1839). These works showcase his sharp social critique and his deep exploration of his characters' inner lives, motivations, and self-interest—a philosophical outlook and character trait often referred to as "Beylism."\n\nBeyond his fiction, Stendhal made significant contributions to the study of human emotion with his treatise De l'amour. Though largely ignored upon its initial publication, the work has since been recognized as a pioneering modern analysis of passionate love, famous for introducing the concept of "crystallization" to describe how the mind attributes perfections to a beloved object. Stendhal passed away in 1842, leaving behind a legacy that profoundly shaped the development of the psychological novel.
