Geskiendenis
Vanadium was originally discovered by Andrés Manuel del Río in 1801.
In 1805, the French chemist Hippolyte Victor Collet-Descotils incorrectly declared that del Río's new element was only an impure sample of chromium.
In 1831, the Swedish chemist Nils Gabriel Sefström rediscovered the element in a new oxide he found while working with iron ores.
Later that same year, Friedrich Wöhler confirmed del Río's earlier work.
