Daniel Gabriel Fahrenheit FRS (/ ˈfærənhaɪt /; German: [ˈfaːʁn̩haɪt]; 24 May 1686 – 16 September 1736) [1] was a physicist, inventor, and scientific instrument maker, born in Poland to a family of German extraction. Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements ...
1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature) 1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the ...
The Fahrenheit scale (/ ˈfærənhaɪt, ˈfɑːr -/) is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). [ 1 ] It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower ...

In 1713, Daniel Gabriel Fahrenheit began experimenting with mercury thermometers. By 1717, he was making them commercially. By 1717, he was making them commercially. [ 3 ] : 79 The superiority of his mercury thermometers over alcohol-based thermometers made them very popular, leading to the widespread adoption of his Fahrenheit scale, the ...
1702 – Guillaume Amontons first calculates absolute zero to be −240 °C using an air thermometer of his own invention (1702), theorizing at this point the gas would reach zero volume and zero pressure. 1714 – Daniel Gabriel Fahrenheit invented the first reliable thermometer, using mercury instead of alcohol and water mixtures

The alcohol thermometer was the earliest efficient, modern-style instrument of temperature measurement. As is the case with many early, important inventions, several people are credited with the invention. These include Ferdinando II de' Medici, Grand Duke of Tuscany, who in 1654 made sealed tubes partly filled with alcohol, with a bulb and ...
