A towering figure in French letters, Chateaubriand’s Mémoires d'outre-tombe is considered a masterpiece of autobiography. His works, such as Atala and René, introduced the 'mal du siècle'—a profound sense of melancholy that defined the Romantic movement. He was also a significant political figure during the Bourbon Restoration. His lyrical prose and focus on nature and the individual's emotions profoundly influenced subsequent generations of French writers.
