French physicist whose most important contributions to physics were his researches on radiant heat made in conjunction with La Provostaye. The two physicists concluded that radiant heat, like light, was a disturbance set up in what was then called the ether and propagated in all directions by transverse waves. They showed in a series of "Mémoires" published in the Annales de Chimie et de Physique that it manifests the characteristic phenomena of reflection, refraction, and polarization, as well as of emission and absorption. They also made a study of the latent heat of fusion of ice, and a careful investigation of the range of applicability of the Dulong-Petit law representing the law of cooling.
He died on 3 May 1885 in Paris, aged 68.
