Anders Celsius (27 November 1701 – 25 April 1744) was a Swedish astronomer that went on to become professor of astronomy at Uppsala University, later going on to found the Uppsala Astronomical Observatory in 1741. In 1742 he proposed the Celsius temperature scale which takes his name. The son of an astronomy professor, Celsius was a talented mathematician from an early age, and studied at Uppsala University, where his father was a teacher. In 1730 he became a professor of astronomy there. Celsius was the first to suggest a connection between the aurora borealis and changes in the magnetic field of the Earth. At Nuremberg in 1733, he published a collection of 316 observations of the aurora borealis made by himself and others. In astronomy, Celsius began the first attempt to measure the magnitude of starlight with a tool other than the human eye. He proposed the Celsius temperature scale in a paper to the Royal Society of Sciences in Uppsala, the oldest Swedish scientific society, founded in 1710. His thermometer was calibrated with a value of 0° for the freezing point of water and 100° for the boiling point. In 1744 he died from tuberculosis.
