Gabriel Daniel Fahrenheit
1718
German physicist, born in Danzig (now
Gdansk, Poland). He settled in Holland and engaged in the manufacture
of meteorological instruments. In 1718 he constructed the first
thermometer employing mercury instead of alcohol. Using this
thermometer he devised the temperature scale now known by his name
and still used in the United States. Fahrenheit also invented a
hygrometer of improved design. He discovered that other liquids
besides water have a fixed boiling point and that these boiling
points vary with changes in atmospheric pressure.
