Daniel Gabriel Fahrenheit, also called Gabriel Daniel Fahrenheit (May 24, 1686 - September 16, 1736), was a physicist and engineer, who most of his life worked in Netherlands and for whom the Fahrenheit scale of temperature is named.
Fahrenheit was born in Danzig (Gdansk) in Poland to German speaking parents.
Upon the early death of his parents he had to take up business training. However, his interest in natural sciences caused him to take up studies and experimentation in that field. Fahrenheit's studies brought him to Amsterdam, where he gave lectures in chemistry. In 1724 he became a member of the Royal Society.
He developed precise thermometers. The Fahrenheit scale was widely used in Europe until a switch to the centigrade or Celsius scale. It is still used by the general population for everyday temperature measurement in the United States.
