    Scandium was discovered by Lars F. Nilson in 1879, in Uppsala, Sweden. Nilson was studying the rare earth elements, attempting to isolate ytterbium from the minerals euxenite and gadolinite.. Part of Nilson’s method required the preparation of erbia (erbium oxide) from the minerals, which was then reacted to form erbium nitrate.
