Anders Celsius (27 November 1701 – 25 April 1744) was a Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 proposed the Celsius temperature scale which bears his name.
In 1742, Anders Celsius defined the temperature scale degree-centigrade which was later named after him. He fixed the boiling point of water at 0 degree and the freezing point at 100 degree. These fixpoints were switched later.
• The Swedish physician, mathematician and astronomer was interessted in mathematic since childhood.
• His father Nils was a professor of astronomy. And even his grandfathers were scholars. Magnus Celsius was a mathematician und Anders Spole was an astronomer.
• Celsius died at the age of only 42 in the middle of his work and only two years after fixing his temperature scale because of tuberculosis.
