Humphry Davy - British chemist and inventor. He discovered several alkali and alkaline earth metals. He also discovered Chlorine and Iodine. He invented the Davy Lamp in 1815 that allowed miners to work safely in the presence of flammable gases.
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.
Humphry Davy (1778–1829), son of an impoverished Cornish woodcarver, rose meteorically to become a leader in the reformed chemistry movement initiated by Antoine-Laurent Lavoisier—albeit a critic of some of its basic premises—and a pioneer in the new field of electrochemistry.
The first electric light in the history was made in the year 1800 by Humphry Davy, an English scientist. He also invented an electric battery while experimenting with electricity. When he connected carbon with the wires of his battery, the carbon glowed hence producing light.
