Scientific career

Eugène-Anatole Demarçay (1 January 1852 – 5 March 1903)[1] was a French chemist. He studied under Jean-Baptiste Dumas. During an experiment, an explosion destroyed the sight in one of his eyes.

He was a spectrum specialist. In 1896, he suspected samples of the recently discovered element samarium were contaminated with an unknown element, which he isolated in 1901, naming it europium. In 1898 he used his skills of spectroscopy to help Marie Curie confirm that she had discovered the element radium.[2]
