Eugène-Anatole Demarçay (January 1, 1852 – March 5, 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 and he isolated europium in 1901. In 1898 he used his skills of spectroscopy to help Marie Curie confirm that she had discovered the element radium.[2]
