Humphry Davy
Summary
Sir Humphry Davy, 1st Baronet, (17 December 1778 29 May 1829) 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. Davy is also credited to have been the first to discover clathrate hydrates in his lab.
In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery.
Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a member of the American Philosophical Society (elected 1810). Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity "one of the best memoirs which has ever enriched the theory of chemistry."
Davy was born in Penzance, Cornwall, in the Kingdom of Great Britain on 17 December 1778, the eldest of the five children of Robert Davy, a woodcarver, and his wife Grace Millett. According to his brother and fellow chemist John Davy, their hometown was characterised by "an almost unbounded credulity respecting the supernatural and monstrous ... Amongst the middle and higher classes, there was little taste for literature, and still less for science ... Hunting, shooting, wrestling, cockfighting, generally ending in drunkenness, were what they most delighted in."
At the age of six, Davy was sent to the grammar school at Penzance. Three years later, his family moved to Varfell, near Ludgvan, and subsequently, in term-time Davy boarded with John Tonkin, his godfather and later his guardian.
