Humphry Davy fue un químico británico. Se le considera el fundador de la electroquímica, junto con Alessandro Volta y Michael Faraday.

Davy contribuyó a identificar experimentalmente por primera vez varios elementos químicos mediante la electrólisis y estudió la energía involucrada en el proceso, desarrolló la electroquímica explorando el uso de la pila de Volta o batería. Entre 1806 y 1808 publicó el resultado de sus investigaciones sobre la electrólisis, en las que había logrado la separación del magnesio, el bario, el estroncio, el calcio, el sodio, el potasio y el boro. En 1807 fabricó una pila con más de 2000 placas doble, con la cual aisló el cloro y demostrando que éste era un elemento químico nuevo . Junto a William Thomas Brande consiguió también aislar al litio de sus sales mediante electrólisis del óxido de litio . En 1805 ganó la medalla Copley. Fue jefe y mentor de Michael Faraday. Creó una lámpara de seguridad que llevó su nombre para las minas y fue pionero en el control de la corrosión mediante la protección catódica. En 1815 inventó la lámpara de seguridad para los mineros.

„Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and of no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown“

— Humphry Davy
Context: Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and of no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown; and in philosophy, the sentiment of the Macedonian hero can never apply, — there are always new worlds to conquer. Discourse Delivered at the Royal Society (30 November 1825), published in Six Discourses delivered before the Royal Society, at their Anniversary Meetings, on the Award of the Royal and Copley Medals, preceded by an Address to the Society on the Progress and Prospects of Science (1827); also in The Edinburgh Review Or Critical Journal (October 1827)

„The true chemical philosopher sees good in all the diversified forms of the external world.“

— Humphry Davy
Context: It is surely a pure delight to know, how and by what processes this earth is clothed with verdure and life, how the clouds, mists and rain are formed, what causes all the changes of this terrestrial system of things, and by what divine laws order is preserved amidst apparent confusion. It is a sublime occupation to investigate the cause of the tempest and the volcano, and to point out their use in the economy of things, — to bring the lightning from the clouds and make it subservient to our experiments, — to produce as it were a microcosm in the laboratory of art, and to measure and weigh those invisible atoms, which, by their motions and changes according to laws impressed upon them by the Divine Intelligence, constitute the universe of things. The true chemical philosopher sees good in all the diversified forms of the external world. Whilst he investigates the operations of infinite power guided by infinite wisdom, all low prejudices, all mean superstitions disappear from his mind. He sees man an atom amidst atoms fixed upon a point in space; and yet modifying the laws that are around him by understanding them; and gaining, as it were, a kind of dominion over time, and an empire in material space, and exerting on a scale infinitely small a power seeming a sort of shadow or reflection of a creative energy, and which entitles him to the distinction of being made in the image of God and animated by a spark of the divine mind. Whilst chemical pursuits exalt the understanding, they do not depress the imagination or weaken genuine feelings; whilst they give the mind habits of accuracy, by obliging it to attend to facts, they likewise extend its analogies; and, though conversant with the minute forms of things, they have for their ultimate end the great and magnificent objects of nature. They regard the formation of a crystal, the structure of a pebble, the nature of a clay or earth; and they apply to the causes of the diversity of our mountain chains, the appearances of the winds, thunder-storms, meteors, the earthquake, the volcano, and all those phenomena which offer the most striking images to the poet and the painter. They keep alive that inextinguishable thirst after knowledge, which is one of the greatest charactics of our nature; — for every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded.
