gadolinium

Gadolinium, element 64, was isolated in 1886 by Swiss chemist Jean Charles Galissard de Marignac. De Marignac found the element in a sample of the mineral gadolinite, hence its name.1 Gadolinite, in turn, is named after Finnish chemist and geologist Johan Gadolin.2

Gadolinium has the chemical symbol Gd.
