In 1766, British physicist isolated and described hydrogen triggering the evolution of science and modern green technology. Henry Cavendish did not invent hydrogen because it occurs naturally. He isolated and studied it as a distinct gas after producing it by reacting metals with acids. He called the gas inflammable air because it could burn. French chemist Antoine Lavoisier later gave it the name hydrogen, meaning water-former. Cavendish also studied the composition of air, the formation of water, electricity and the density of Earth. His experiments became part of the development of modern chemistry and physics.
Henry Cavendish was a British physicist and chemist whose research covered gases, air, water, electricity, heat and gravity. He was born on October 10, 1731, in Nice, France, and died on February 24, 1810, in London, England.
