Discovery

It was discovered by the physician and chemist Gabriel Sefström (Falun, Sweden) in 1830. It had originally been discovered by the Spanish mineralogist Andres Manuel del Rio y Fernandez (Mexico City, Mexico) in 1801, who named it erythronium, after the plant of that name whose flowers have many beautiful colors. Del Rio later decided that it was really chromium in his lead sample. Vanadium metal was first isolated by the English chemist Henry Enfield Roscoe in 1869.

Name Derived From

The name derives from the Scandinavian goddess of love and beauty, Freyja Vanadis, because of its many beautiful multicolored compounds.
