Georges Urbain
April 12th 1872 - November 5th 1938
Georges was born in France and discovered Lutetuim in 1907.
In 1878, the Swiss chemist Jean Charles de Marignac separated a new substance from the rare earth elements and named it ytterbium. In 1907 and 1908, however, the French chemist Georges Urbain and the Austrian chemist Carl Auer von Welsbach independently separated Marignac's ytterbium into two elements, which are now called ytterbium and lutetium.
