Anders Celsius (1701-44) invented and gave his name to the Celsius thermometer, also known as the centigrade thermometer.  The scale on the Celsius thermometer is a simplification of the earlier Fahrenheit scale, showing the freezing point of water at zero and the boiling-point at 100 degrees.
Celsius was born at Uppsala, in Sweden and became a professor at Uppsala University, where his uncle Olaf Celsius, had been a teacher of Linnaeus, the famous botanist.  He was a leading astronomer of his time (he built the observatory at Uppsala) and one of the first to advocate the adoption of the Gregorian calendar in Sweden.
