| biography:
| Chemist, born in St Thomas, West Indies. He studied medicine in Paris but was soon attracted to chemistry. By 1851 he had become professor of chemistry at the Ecole Normale in Paris, and shortly afterwards professor at the Sorbonne. It was he who first produced aluminium (1855) and platinum in commercial quantities, by reduction of chlorides with sodium metal. His interest in high temperature reactions led to the discovery of reversible changes in relative molecular mass with temperature, which he termed dissociations. |
