Davys laboratory assistant, Michael Faraday, went on to enhance Davys work and would become the more famous and influential scientist. Davy is supposed to have even claimed Faraday as his greatest discovery. Davy later accused Faraday of plagiarism, however, causing Faraday (the first Fullerian Professor of Chemistry) to cease all research in electromagnetism until his mentor's death.
According to one of Davy's biographers, June Z. Fullmer, he was a deist.
Of a sanguine, somewhat irritable temperament, Davy displayed characteristic enthusiasm and energy in all his pursuits. As is shown by his verses and sometimes by his prose, his mind was highly imaginative; the poet Coleridge declared that if he "had not been the first chemist, he would have been the first poet of his age", and Southey said that "he had all the elements of a poet; he only wanted the art." In spite of his ungainly exterior and peculiar manner, his happy gifts of exposition and illustration won him extraordinary popularity as a lecturer, his experiments were ingenious and rapidly performed, and Coleridge went to hear him "to increase his stock of metaphors." The dominating ambition of his life was to achieve fame; occasional petty jealousy did not diminish his concern for the "cause of humanity", to use a phrase often employed by him in connection with his invention of the miners' lamp. Careless about etiquette, his frankness sometimes exposed him to annoyances he might have avoided by the exercise of tact.
