Who invented hydrogen?

The element hydrogen occurs naturally and was not invented. It is a colorless and odorless gas, has the lowest density of all gases and is the most abundant element in the universe. Hydrogen is the source of energy for the sun and is also present in most stars.

Although the existence of hydrogen was observed in the early 1500s when it was generated by Theophrastus Paracelsus, English scientist Henry Cavendish was the first person to determine its status as an element in 1766. As one of the elements in water, it was named hydrogen, meaning "water-former" from the Greek words "hydro" and "genes," by Antoine Lavoisier in 1783.
