Thermometer with Fahrenheit (symbol °F) and Celsius (symbol °C) units. In 1714, scientist and inventor Daniel Gabriel Fahrenheit invented a reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name.
Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements between different observers using different instruments. [2] Fahrenheit is also credited with inventing mercury-in-glass thermometers more accurate and superior to spirit-filled thermometers at the time.
1866 — Thomas Clifford Allbutt invented a clinical thermometer that produced a body temperature reading in five minutes as opposed to twenty. [14] 1871 — William Siemens describes the Resistance thermometer at the Bakerian Lecture; 1874 — Herbert McLeod invents the McLeod gauge
(Galileo did invent a thermometer called Galileo's air thermometer, more accurately called a thermoscope, in or before 1603.) [1] The instrument now known as a Galileo thermometer was invented by a group of academics and technicians known as the Accademia del Cimento of Florence, [ 2 ] who included Galileo's pupil, Torricelli and Torricelli's ...
The first sealed thermometer was constructed in 1654 by the Grand Duke of Tuscany, Ferdinand II. [1]: 19 The development of today's thermometers and temperature scales began in the early 18th century, when Daniel Gabriel Fahrenheit produced a mercury thermometer and scale, both developed by Ole Christensen Rømer.
Philo of Byzantium is credited with the construction of the first thermoscope (or Philo thermometer), an early version of the thermometer. [6] It is also thought, but not certain, that Galileo Galilei discovered the specific principle on which the device is based and built the first thermoscope in 1593.
Temperature measurement using modern scientific thermometers and temperature scales goes back at least as far as the early 18th century, when Daniel Gabriel Fahrenheit adapted a thermometer (switching to mercury) and a scale both developed by Ole Christensen Rømer. Fahrenheit's scale is still in use in the United States for non-scientific ...
1638 – Robert Fludd describes thermometer with a scale, using air thermometer principle with column of air and liquid water. 1650 – Otto von Guericke designed and built the world's first vacuum pump and created the world's first ever vacuum known as the Magdeburg hemispheres to disprove Aristotle's long-held supposition that 'Nature abhors ...
