In 1714, Daniel Gabriel Fahrenheit, a German physicist who was living in Holland and operating an instrument business, developed a mercury-in-glass thermometer and the temperature scale that still carries his name. His original scale had two fixed points: 0° was the lowest temperature that he could achieve in a solution of ice, water, and salt, and 96° was what he believed was the normal temperature of the human body (though this was later determined to be 98.6°). Based on this scale, he calculated that the freezing poin
