| biography:
| Chemist, born in Rouen, NW France. He trained in medicine and science at Paris, and later became director of its Ecole Polytechnique. His name is now most linked with the Dulong–Petit law (1819), devised in association with Alexis Thérèse Petit (1791–1820), which relates the specific heat capacity of a solid element to its relative atomic mass, and which for over a century was a valuable route for finding approximate atomic weights. |
