In a house at 54 Rue du Château, surrealist poets Marcel Duhamel, Jacques Prévert, and Yves Tanguy invented 'Le Cadavre Exquis' (The Exquisite Corpse). This parlor game involved players writing a phrase or drawing an image on a piece of paper, folding it to conceal the contribution, and passing it to the next person. The game received its name from the very first poetic sentence generated by the method: 'Le cadavre exquis boira le vin nouveau' (The exquisite corpse will drink the new wine).

This technique proved that collective, unguided subconscious play could generate highly resonant, haunting poetic imagery that no individual conscious mind could ever plan. It became a crucial methodology for surrealist writers, demonstrating how bypassing individual artistic ego creates a pure, shared dream-logic.
