Scheelite was discovered by Swedish chemist Carl William Scheler in 1781 and a new element acid tungstic acid was extracted. Wolframite was also extracted from wolframite discovered by Spanish Depulya in 1783. In the same year, tungsten powder was obtained for the first time by reducing tungsten trioxide with carbon, and the element was named.
