Humphry Davy
British chemist
Summary
Updated 2026-05-29
The Davy lamp made him a household name, but Davy's real flex was electrifying chemistry itself—isolating potassium, sodium, and half the periodic table before most people knew what an element was.
Biography
About
Sir Humphry Davy, 1st Baronet was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. He is credited with discovering clathrate hydrates.
