description: "Pierre Louis Dulong FRS FRSE was a French physicist and chemist. He is remembered today largely for the law of Dulong and Petit, although he was much-lauded by his contemporaries for his studies into the elasticity of steam, conduction of heat, and specific heats of gases. He worked most extensively on the specific heat capacity and the expansion and refractive indices of gases. His collaboration with Alexis Thérèse Petit led to the discovery of the Dulong–Petit law on heat capacity."
