Sir Humphry Davy

Born in Penzance, Cornwall, in 1778, Humphry Davy rose from modest beginnings to become one of Britain's most celebrated chemists. In Bristol he carried out bold experiments on gases, including nitrous oxide, and his lively scientific lectures soon made him a star at the Royal Institution in London.

Davy used electricity as a powerful tool for chemistry and is known for isolating elements including sodium, potassium, calcium, and magnesium. His research and demonstrations helped bring science to a wide public, and his fame spread beyond the laboratory into literary and social circles.

In 1815 he devised the Davy lamp, a safety lamp for miners that became one of his best-known practical inventions. He also played an important part in the early career of Michael Faraday, who began as his assistant. Davy died in 1829, but his mix of showmanship, curiosity, and practical invention left a lasting mark on modern science.
