LAVOISIER

In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element but a compound of oxygen and inflammable air, or hydrogen as it is now known. To support his claim, Lavoisier decomposed water into oxygen and inflammable air.

Answer 2

Lavoisier

Water is not an element: Lavoisier. Of the four elements of the ancients, water is the only one which is a pure chemical substance, albeit a compound and not an element.

Hence, Lavoisier was the scientist who proved that hydrogen is a compound and not an element.
