Person

Lars Fredrik Nilson

A man with a neatly groomed beard and mustache, dressed in formal attire, stands against a dark background, exuding an air of scholarly respectability.

Swedish chemist (1840–1899) at Uppsala who specialised in the messy chemistry of the rare-earth minerals from Scandinavian pegmatites. He isolated scandium in 1879 while trying to purify ytterbium from euxenite and gadolinite. He had not read Mendeleev's predictions when he made the discovery; the match with eka-boron was pointed out by his colleague Per Teodor Cleve.
