Who is the founder of vanadium?

Answer 1

Vanadium is an element. Elements get discovered, they do not get founded. Organizations have founders, elements don't.

Answer 2

The element vanadium was discovered in 1801 by the Spanish mineralogist Andrés Manuel del Río. He initially named the element "panchromium" but later withdrew his claim due to a mistaken belief that he had discovered a form of chromium. The element was eventually rediscovered and officially named vanadium in 1830 by the Swedish chemist Nils Gabriel Sefström.
