Statue of Humphry Davy

At the top of Market Jew St is a statue to Penzance's most famous son, Humphry Davy (1778-1829), the pioneering 'chemical philosopher', amateur poet and fanatical trout fisherman. Davy was responsible for an astonishing number of scientific advances: the discovery of six new elements (including potassium, sodium and strontium), the invention of the miner's safety lamp, and the use of nitrous oxide (or laughing gas) as a medical anaesthetic.

He also penned reams of amateur poetry and befriended some of the 19th century's best-known Romantic writers, including Samuel Taylor Coleridge, although whether it was Davy's amateur verse or his ready supply of chemical narcotics that most interested Coleridge is a moot point.
