Samarium, element 62, is named after samarskite, the mineral from which it was first isolated. The mineral, in turn, takes its name from a 19th century Russian mining official, Vasily Samarsky-Bykhovets.1
Samarium was isolated in 1879 by French chemist Paul Émile Lecoq de Boisbaudran who gave the element its name.2
Samarium has the chemical symbol Sm.
