The earliest mercury thermometer was constructed by Daniel Gabriel Farenheit (Poland) (1686-1736) in 1714.
Farenheit had settled in Amsterdam in 1701 before travelling around Europe, meeting instrument makers and scientists. It was during this period he invented the mercury thermometer. He returned to Amsterdam in 1717. He published his method for thermometer construction in the journal 'Philosophical Transactions of the Royal Society of London' in 1724. During the same year he was admitted to the Royal Society (UK).
