Portrait by Thomas Phillips, 1821 - Sir Humphry Davy, 1st Baronet FRS MRIA FGS (1778 –1829) was a Cornish chemist & inventor. He is probably best remembered today for his discoveries of several alkali & alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine & iodine. In January 1819, Davy was awarded a baronetcy, this was, at the time, the highest honour ever conferred on a man of science in Britain.


Michael Faraday, FRS was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.


The Davy Lamp was a milestone in mine safety. Invented by Sir Humphrey Davy in 1816 it was seen as the solution to mine explosions due to methane. He discovered that a fine mesh screen would allow oxygen & explosive gas to penetrate but would not allow the flame to migrate outside the mesh. Explosions were reduced. The lamp also was used as a safety device burning brighter & higher as more gas was present & lower as carbon dioxide built up. It was used all over the world & still is.


The invention of the Davy Lamp, a mining innovation! Humphry Davy was born on this day.

The 10 best physicists

Michael Faraday Faraday (1791-1867) became one of the greatest scientists of his day thanks to the patronage of the eminent English chemist Humphry Davy, who hired him as an assistant in 1813. Faraday went on to establish the idea of the electromagnetic field and discovered electromagnetic induction and the laws of electrolysis. His electromagnetic devices formed the foundation of electric motor technology.


Humphry Davy invented an electric light. He used a electric battery, carbon, and wires. This was the first time that someone had used electricity to produce light.
