The foundation of the Société Anonyme des Pâtes de Verre d'Argy-Rousseau in Paris in 1921 ushered in an epoch of creative exuberance which spawned a profusion of vases, bowls, lamps, sculptures and other decorative objects. The career of this remarkable genius is retraced in details : his education, his inventiveness, his artistic development, his commercial succes, and his later difficulties during the Depression years. The process by which his pâtes de verre were produced, from initial desing to final molding, is fully described. And a Catalogue Raisonné illustrating almost 350 pieces shows the extraordinary diversity of Argy-Rousseau's inspiration.
