DiscoveryDiscovered  by the Spanish chemists and mineralogists Juan José and Fausto Elhuyar (Vergara, Spain) in 1783. Earlier (1781) the Swedish chemist Carl Wilhelm Scheele had discovered tungstic acid in a mineral now known as scheelite, and his countryman Torbern Bergman had concluded that a new metal could be prepared from the acid. 
Name Derived FromSwedish tung sten meaning 'heavy stone'

The names tungsten and wolfram have been used for the metal since its discovery, though everywhere Jön Jacob Berzelius' symbol [ W] prevails. In British and American usage tungsten is preferred; in Germany and a number of other European countries wolfram is accepted.
