1778-1829. English chemist. As a laboratory
assistant in Bristol in 1799, he discovered
the respiratory effects of laughing gas
(nitrous oxide). He discovered, by
electrolysis, the elements sodium, potassium,
calcium, magnesium, strontium, and barium. He
invented the `safety lamp' for use in mines
where methane was present, enabling the
miners to work in previously unsafe
conditions. In 1802 he became professor at
the Royal Institution, London. He was elected
President of the Royal Society in 1820.
