Georges Urbain



  He was a French chemist and President of the Société de Chimie who discovered and named lutetia (discovery honors are shared with Welsbach and James). Urbain had spent years analyzing complex mixtures of rare earths, only to discover that analysis could be rapidly performed using the brand-new X-ray techniques of Moseley.
