The story behind the name

Inventor of the Celsius temperature scale

Anders Celsius, who lived from 1701 to 1744, was a Swedish astronomer and professor of astronomy at Uppsala University in Sweden. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 he proposed the Celsius temperature scale which takes his name. The scale was later reversed in 1745 by Carl Linnaeus, one year after Celsius’ death.
