Louis Jouvet (1887-1951) was a French actor, director, and theatre manager, a central figure in 20th-century theatre. Trained at Jacques Copeau's Théâtre du Vieux-Colombier, he developed a rigorous and innovative style. He was one of the founders of the "Cartel des Quatre," an alliance of directors that aimed to renew the Parisian stage. His career is inextricably linked to the playwright Jean Giraudoux, whose masterpieces he staged, such as *The Trojan War Will Not Take Place* and *The Madwoman of Chaillot*. Also memorable were his productions of Molière, particularly *The School for Wives*, and his success in Jules Romains' *Knock, or the Triumph of Medicine*. In parallel, he had a notable film career, playing iconic roles in films such as Marcel Carné's *Hôtel du Nord* and Henri-Georges Clouzot's *Quai des Orfèvres*. From 1934, he directed the Théâtre de l'Athénée, which today bears his name, and was awarded the title of Grand Officer of the Legion of Honour.
