Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878. He heated erbium nitrate until it decomposed and then extracted the residue, which contained an unknown white powder that he named ytterbium oxide. The pure metal was not produced until 1953. The element is named after Ytterby, a village in Sweden. Four elements are named after this town, the others being yttrium, terbium, and erbium.
