Sir Humphry Davy, 1st Baronet PRS MRIA FGS FRS (17 December 1778 – 29 May 1829) was a Cornish chemist and inventor,[1] who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine. He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonished that it made him laugh, so he nicknamed it "laughing gas", and wrote about its potential anaestheticproperties in relieving pain during surgery.[2]
Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity[3] "one of the best memoirs which has ever enriched the theory of chemistry."[4] He was a Baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), and Fellow of the Geological Society (FGS). He also invented the Davy lamp and a very early form of incandescent light bulb.
He joked that his assistant Michael Faraday was his greatest discovery.
