Centigrade temperature scale developed

The centigrade temperature scale is developed by Jean-Pierre Christin

19 May, 1743

The centigrade temperature scale is developed by Jean-Pierre Christin on 19th May 1743.

Christin’s contribution was reversing the Celsius thermometer scale. As per his proposal, the boiling point of water was to be at 100 degrees and ice melting at 0 degrees. Originally, the values were the other way around.

Christin was a founding member and long time secretary of Académie des sciences, belles-lettres et arts de Lyon at Lyon, France. Before the French Revolution, his thermometer was known as the Thermometer of Lyon.
