Doucet’s passion for collecting extended beyond design and visual art to the world of literature. His legendary book collection dedicated to art history comprised 1.4 million volumes and documents, which still today form the foundation of the art history archives at the Bibliothèque Nationale de France, benefiting scholars from across the globe. On the advice of Surrealist poets André Breton and Louis Aragon, Doucet began acquiring rare manuscripts and first editions by literary giants such as Baudelaire and Apollinaire. These meticulously curated volumes reflected his belief in the written word as a powerful art form. Significant portions of his collection are preserved today in the Bibliothèque littéraire Jacques Doucet in Paris. His dedication to the literary arts left a lasting impact on cultural preservation and academic study, securing his legacy as a pivotal figure in both art and literature. His influence continued long after his death in 1929, inspiring designers and tastemakers like Yves Saint Laurent, Pierre Bergé, and Karl Lagerfeld, who revered Doucet’s aesthetic and lifestyle.
