Hydrogen's history
Hydrogen was first discovered in the early 1500s by alchemist Paracelsus when he noticed bubbles given off when iron fillings were added to sulfuric acid were flammable, and then again in 1671 by Robert Boyle but neither followed through with their research which is why Henry Cavendish receives all the credit for its discovery in 1766 where he collected the bubbles and showed that they were different from other gases.
