Hydrogen
Hydrogen gas was first artificially produced in the early 16th century, via the mixing of metals with acids. In 1766-81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance, and that it produces water when burned, a property which later gave it its name: in Greek, hydrogen means "water-former".
