In 1901 Eugene-Anatole Demargay in Paris showed that the samples of samarium and gadolinium produced until that time harboured yet another rare-earth element, which he named generously after all of Europe europium. This element is in fact one of the most naturally abundant of the group the Earth s crust contains twice as much europium as tin. It is harvested today largely for a very special and useful property its emission of very pure red and blue light.

The final isolation from the "cerite tree" occurred in 1901 when Eugene-Anatole Demargay (1852-1904) reported the separation of europium (Eu). The final isolation from the "ytterbite tree" was reported in 1907 when lutetium (Lu) was separated from the more abundant ytterbium (Yb). The element was discovered by Georges Urbain (1872-1938), at the Sorbonne, and independently...

Eugene-Anatole Demargay in Paris just before the end of the 19 century carried out a series of fractional crystallization experiments, using double nitrates of magnesium and samarium. During these experiments europium was discovered.
