Sir Humphry Davy (1778-1829), English chemist; President of the Royal Society, 1820; made many important chemical discoveries. He assisted Thomas Wedgwood in his experiments with light upon silver and described them in the Journal of the Royal Institution (1802); in the same year he discovered that silver chloride gave better results than silver nitrate in the preparation of a sensitive surface.
