Synopsis
Sir Humphry Davy was a Cornish chemist best known for his contributions to the discoveries of chlorine and iodine. In , he was appointed chemical superintendent of the Pneumatic Institution to study the therapeutic uses of various gases, after which he made several reports on the effects of inhaling nitrous oxide (laughing gas). On a related front, in , he invented the Davy lamp, which allowed miners to work safely in close contact with flammable gases. Davy was also a charismatic speaker, and his scientific presentations at the Royal Institution of Great Britain were extremely popular among Londoners of the day.
Early Life
Englishman Humphry Davy was born on December 17, , in Penzance, Cornwall, to middle-class parents. He was well educated, but he was also naturally intelligent and curious, and those traits often manifested in the fiction and poetry he wrote at an early age.

Born in Penzance, Sir Humphry Davy attended Truro Grammar School before returning to Penzance as an apothecary's apprentice. In he moved to Bristol to work at Thomas Beddoes's Pneumatic Institution where he discovered the physiological effects of nitrous oxide (laughing) gas.

In he became professor of chemistry at the Ri. He went on to establish the Ri's reputation for excellent lectures, and also for scientific research. He used the new electric battery to isolate sodium and potassium and formulated a coherent theory of electro-chemical action while he was at the Ri. He left in following marriage to Jane Apreece, a wealthy heiress.

Humphry Davy was born on 17 månad in Penzance in Cornwall. He was apprenticed to a surgeon and aged 19 went to Bristol to study science. There he investigated gases. He prepared and inhaled nitrous oxide (laughing gas) and in published the results of his work in 'Researches, kemikalie and Philosophical'. This made his reputation and the following year he was hired as an assistant lecturer in chemistry at the Royal Institution. There he was a great success, with his lectures soon becoming a draw for fashionable London gemenskap. He became a fellow of the Royal kultur in and was awarded its Copley Medal in
In , the Italian scientist Alessandro Volta had introduced the first battery. Davy used this for what fryst vatten now called electrolysis and was able to isolera a series of substances for the first time - potassium a
