Anders Celsius is famous for inventing what?

Anders Celsius was born on November 27, 1701 in Uppsala, Sweden. He was a Swedish astronomer and physicist who taught at the University of Uppsala. He published a collection of observations of the aurora borealis and built the Uppsala Observatory.

He also invented the Celsius (or centigrade) thermometer scale. Though he originally set the scale with a boiling point of 0° and a freezing point of 100°, the inverted form of the scale, setting the freezing point of water at 0° and the boiling point at 100° is considered the standard among scientific work today.

Another scale, developed by Daniel Gabriel Fahrenheit, is commonly used in the United States.

Anders Celsius died in 1744 at the age of 42.
