The chemist and inventor Davy is recognised for his groundbreaking work with gases and electrolysis. In 1807 he demonstrated the existence of potassium, sodium and chlorine with a galvanic battery. He also experimented with diamond combustion and invented the miner's safety lamp in 1815. He was rewarded for his contribution to science with a baronetcy (1818) and the presidency of the Royal Society (1820).
