Gallium was discovered in 1875 by the French chemist Lecoq de Boisbaudran. Spectroscopic examination of concentrates from a Pyrenea blende revealed emission lines whose positions corresponded to those predicted for "eka-aluminum", a missing element between aluminum and indium in Mendeleev's Periodic Table of the elements. Boisbaudran subsequently prepared this new element by electrolysis of caustic solutions and observed some of its properties. He named it gallium from the Latin Gallia in honor of his fatherland.
