Humphry Davy

Sir Humphry Davy, 1st Baronet FRS MRIA FGS (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.

Davy was born in Penzance in Cornwall, United Kingdom, on 17 December 1778. The parish register of Madron (the parish church) records ‘Humphry Davy, son of Robert Davy, baptized at Penzance, January 22nd, 1779.’ Robert Davy was a wood carver at Penzance, who pursued his art rather for amusement than profit. As the representative of an old family (monuments to his ancestors in Ludgvan Church date as far back as 1635), he became possessor of a modest patrimony. His wife, Grace Millet, came from an old but no longer wealthy family. Her parents died within a few hours of each other from malignant fever, whereupon Grace and her two sisters were adopted by John Tonkin, an eminent surgeon in Penzance. Robert Davy and his wife became the parents of five children — two boys, Humphry, the eldest, and John, and three girls.
