 Humphry Davy   (Site not responding. Last check: 2007-11-07)
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.
In 1801 Davy was appointed—first as a lecturer, then as a professor of chemistry—to the Royal Institution in London, which he molded into a center for advanced research and for polished demonstration lectures delivered to audiences largely made up of fashionable gentlemen and ladies.
Davy became a fellow of the Royal Society in 1803 and served as its president from 1820 to 1827.

Humphey Davy was born in Penzance on 17th December 1788, the son of a woodcarver.
Davy concluded that the production of electricity in simple electrolytic cells was the result of a chemical reaction, and that because of this reaction it offered the best means of decomposing all substances to their elements.
Davy did not patent his invention, he wrote that "...my sole object was to serve the cause of humanity and if I have succeeded I am rewarded in the gratifying of having done so".

Davy wrote 1816: "No, my good friend, I never thought of such a thing; my sole object was to serve the cause of humanity, and if I succeeded I am amply rewarded in the gratifying of having done so".

 Who Invented the Flame Safety Lamp
The invention of the flame safety lamp is often attributed to Sir Humphrey Davy, the renowned Cornish scientist and scholar.
Davy attempted at least three designs of safety lamp, and reported his early results to the Royal Institution on November 9, 1815.
Clanny's first lamp, which he developed in 1813 and presented to the Royal Society in a lecture, used a water trap at the inlet and outlet to the lamp, and a set of bellows was used to force air through the lamp to keep the flame alight.

 Safety Lamp History
In 1815, Davy discovered that if two vessels were filled with explosive gas, they might be connected together by a narrow tube, and the gas in one of the chambers could be exploded without transmitting the explosion to the adjoining chamber.
Davy built a lamp that totally enclosed the flame with a cylinder of gauze.
Davy's wire gauze principle was used in almost every type of flame safety lamp that was developed for near 200 years.

It occurred to me, that supposing nitrous oxide to be a stimulant of the common class, it would follow that the debility produced in consequence of excessive stimulation by a known agent, ought to be increased after excitement from nitrous oxide.
The pain in the head every minute increased; I was neither feverish nor thirsty; my bodily and mental debility were excessive, and the pulse feeble and quick.
As I recovered my former state of mind [following a later experiment in which Davy inhaled copious quantities of nitrous oxide], I felt an inclination to communicate the discoveries I had made during the experiment.

 Chemical theory, volcanism: Davy
DAVY was a contemporary of ALEXANDER VON HUMBOLDT and the last major representative of the assumption of a cold interior of the earth, that was usually linked to the ideal that the subterranean caves were inhabitable.
Both HUMBOLDT and the British chemist Sir HUMPHREY DAVY were asked in public several times whether they would be ready to embark on such an underground expedition.
Although DAVY did not assume that the earth is hollow, as HALLEY still did, but thought that the core of the earth consists of non-oxidated masses of metalloids of alkalis and earths, he triggered speculations about a "journey to the centre of the earth" by assuming a cold interior of the earth.
