Henry Cavendish

1731-1810

He was an English chemist and physicist who discovered “inflammable air” (hydrogen). He conducted very precise experiments of gases and independently discovered nitrogen. He also observed a small amount of inert gas as a constituent of the atmosphere (which proved one hundred years later to be argon). Cavendish never relinquished the phlogiston theory, despite his genius and the over-whelming evidence furnished by Lavoisier.
