Baron Auer von Welsbach
|He was an Austrian chemist who separated didymia into praseodymium and neodymium. Welsbach invented the gas mantle known by his name, by impregnating mantle fabric with refractory thorium and cerium salts. He is credited with the independent discovery of lutetium, which he called “cassiopeium.”
