Davy was later educated in the Cornwall's county town of Truro and this was followed by an apprenticeship to a Penzance surgeon. In 1797, Davy took up chemistry and was taken on as an assistant at the Medical Pneumatic Institution in Bristol. It was here he experimented with various new gases by inhaling them which nearly cost him his life on more than one occasion, eventually though, this experimentation led to the discovery of the anesthetic effect of what we know as laughing gas.
This lamp allowed coal to be mined from deep coal seams reducing the dangers of explosions from methane gas. The lamp, consisted of a wick with the flame enclosed inside a mesh screen, Davy discovered that if the mesh was fine enough, it would not ignite the methane.
Sir Humphry Davy died in Geneva, Switzerland, on 29 May 1829
