Lazare Duvaux (c.1703 – 24 November 1758) was a Parisian marchand-mercier, among the most prominent designers and purveyors of furnishings, gilt-bronze-mounted European and Chinese porcelains, Vincennes porcelain and later Sèvres porcelain and all the small, refined luxuries that appealed to Mme de Pompadour, one of his most prominent clients, who entrusted the furnishing of her many châteaux to Duvaux. Another prominent client was Pierre Victor, Baron de Besenval de Brunstatt, who furnished his residence in Paris, the Hôtel de Besenval, with the help of Lazare Duvaux. Lazare Duvaux was retrieved from posthumous obscurity when his daybook covering the decade 1748-1758 was published in 1873; it remains a central document of the decorative arts of the mid-18th century.
