# Humphry Davy

> He ran electricity through compounds and pulled out elements no one had seen before — potassium, sodium, calcium, barium, magnesium, boron — then proved chlorine and iodine were elements too. Before that, he inhaled nitrous oxide, laughed his head off, and told surgeons they could use it to kill pain.

## Bio

Humphry Davy was born 17 December 1778 in Britain and became the chemist who invented electrochemistry. In 1799 he experimented with nitrous oxide, found it made him laugh, nicknamed it "laughing gas," and wrote about its potential as an anaesthetic for surgery. Then in 1807 he used electricity to isolate potassium and sodium for the first time, and the following year calcium, strontium, barium, magnesium, and boron. He also discovered the elemental nature of chlorine and iodine, studied the forces in these separations, invented the Davy lamp and an early arc lamp, and is credited with discovering clathrate hydrates. Berzelius called his 1806 Bakerian Lecture "one of the best memoirs which has ever enriched the theory of chemistry." He became a baronet, President of the Royal Society, and died 29 May 1829.
