Davy was born in Penzance, Cornwall, in the Kingdom of Great Britain on 17 December 1778, the eldest of the five children of Robert Davy, a woodcarver, and his wife Grace Millett. According to his brother and fellow chemist John Davy, their hometown was characterised by "an almost unbounded credulity respecting the supernatural and monstrous ... Amongst the middle and higher classes, there was little taste for literature, and still less for science ... Hunting, shooting, wrestling, cockfighting, generally ending in drunkenness, were what they most delighted in." At the age of six, Davy was sent to the grammar school at Penzance. Three years later, his family moved to Varfell, near Ludgvan, and subsequently, in term-time Davy boarded with John Tonkin, his godfather and later his guardian. On leaving Penzance grammar school in 1793, Tonkin paid for Davy to attend Truro Grammar School to finish his education under the Rev Dr Cardew, who, in a letter to Davies Gilbert, said dryly, "I could not discern the faculties by which he was afterwards so much distinguished." Yet, Davy entertained his school friends by writing poetry, composing Valentines, and telling stories from One Thousand and One Nights. Reflecting on his school days in a letter to his mother, Davy wrote, "Learning naturally is a true pleasure; how unfortunate then it is that in most schools it is made a pain." "I consider it fortunate," he continued, "I was left much to myself as a child, and put upon no particular plan of study ... What I am I made myself." His brother, moreover, claimed Davy possessed a "native vigour" and "the genuine quality of genius, or of that power of intellect which exalts its possessor above the crowd."
