I wish I knew who invented temperature measurement!
You may be surprised how many warm bodies got involved in the creation of temperature measurement as we know it today. We posted a video explaining this history, but here you can read the timeline of this evolution.
- 1593 – Galileo Galilei made the first thermoscope, a device to indicate temperature differences.
- 1612 – Then Santorio Santorio, Galileo’s friend, created the first thermometer.
- 1654 – Ferdinand II, Grand Duke of Tuscany, produced the first liquid-in-glass meter.
- 1664 – Robert Hooke proposed the freezing point of water as a zero point.
- 1702 – And Ole Roemer established two fixed points, Hooke’s zero points and the boiling point of water.
- 1714 – Daniel Gabriel Fahrenheit built the first mercury-in-glass thermometer and invented the first standard scale, Fahrenheit.
- 1730 – René Antoine Ferchault de Réaumur created another scale, naming the freezing point of water as zero degrees and the boiling point as 80 degrees. We don’t use this scale anymore.
- 1742 – Anders Celsius, a Swedish scientist, invented the Celsius scale using the freezing point as 100 degrees and the boiling point as zero. Later, Jean Pierre Christin switched these points to make the scale we use today.
- 1848 – And finally, Sir William Thomson, also known as Lord Kelvin, created the absolute temperature scale.
