Biographical Note for fahrenheit

Fahrenheit, Daniel Gabriel (1686–1736), German physicist. Fahrenheit devoted his career mostly to the making of precision scientific instruments. In 1709 he developed an alcohol thermometer, superseding it with a mercury thermometer in 1714. His most important achievement was his development, from the work of Olaus Roemer, of the thermometric scale that bears his name.
