Chemist and Inventor.
Sir Humphry Davy, 1st Baronet (17 December 1778 – 29 May 1829) was a British chemist and inventor. He is probably best remembered today for his discoveries of several alkali and alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine and iodine. Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity "one of the best memoirs which has ever enriched the theory of chemistry." This paper was central to any chemical affinity theory in the first half of the nineteenth century. In 1815 he invented the Davy lamp, which allowed miners to work safely in the presence of flammable gases.

"In prominent alliance with his concept, Davy celebrated a natural-philosophic deism, for which his critics did not attack him, nor, indeed, did they bother to mention it. Davy never appeared perturbed by critical attacks on his "materialism" because he was well aware that his deism and his materialism went hand in hand; moreover, deism appeared to be the abiding faith of all around him."
