Lars Fredrik Nilson, while working on rare earths, employs spectroscopic analysis in 1879 to discover scandium's oxide, scandia (named for Scandinavia"), in the rare-earth minerals gadolinite and euxenite, which occur only in Scandinavia.

During this time he also studies the gas density of metals which make it possible to determine the valence of various metals.

Nilson was born in Skönberga parish in Östergötland, Sweden.

His father, Nikolaus, was a farmer.

The family had moved to Gotland when Lars Fredrik was young.

After graduating from school, Lars Fredrik had enrolled at Uppsala University, and there he studied the natural sciences.

His talent for chemistry drew attention from chemistry professor Lars Svanberg, who was a former student of Jöns Jakob Berzelius.

In 1874 Nilson had became associate professor of chemistry, and could now devote more time to research.
