Juan José and Fausto de Elhuyar isolate tungsten in 1783 at the Royal Patriotic Seminary of Bergara from wolframite, reducing tungstic acid with charcoal. They publish their results in *Análisis químico del volfram y examen de un nuevo metal que entra en su composición* (1783). It is the only element of the periodic table first isolated in Spain. Carl Wilhelm Scheele had discovered tungstic acid in 1781 but failed to isolate the metal; Peter Woulfe had proposed the element's existence in 1779. The Elhuyars were the first to obtain the metal in pure form and to characterize it.
