|SIR HUMPHREY DAVY|
Born: in Penzance, on Dec 17, 1778
Died: May 29, 1829 in Geneva
He investigated gases; preparing and inhaling nitrous oxide (laughing gas),
Davy discovered a number of chemical elements - including sodium and potassium in 1807 - and investigated chlorine and its oxides. Through electrolysis, he eventually discovered magnesium, calcium, strontium, and barium in 1808.He was Knighted in 1812, and he received special dispensation from Napoleon to travel across France from 1813 to 1815, during which time he discovered 'X' - later called iodine.
Davy's most important investigations were devoted to electrochemistry. He found that when he passed electrical current through some substances, these substances decomposed, (a process later called electrolysis).
Davy separated the candle flame - which helped to light the miner's way (in the coal mines of Newcastle) from methane gas, and his lamp later became widely used, and known as the Davy lamp
