George Urbain (1872-1938), a French chemist who did most of his research on the isolation, separation, and properties of the rare earths. As a result of this work he developed a series of very efficient methods for separating them, determine their spectrum, magnetic properties, and atomic masses; he isolated europium and gadolinium and determined their correct atomic mass, and discovered the elements lutetium and celtium (hafnium). In addition, he carried on a detailed study of the phenomenon of efflorescence of saline hydrates.
