Anders Celsius (November 27, 1701 – April 25, 1744) was a Swedish astronomer. Celsius was born in Uppsala in Sweden. 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. At Nuremberg in 1733 he published a collection of 316 observations of the aurora borealis made by himself and others over the period 1716-1732. In Paris he advocated the measurement of an arc of the meridian in Lapland, and in 1736 took part in the expedition organized for that purpose by the French Academy of Sciences, led by the French mathematician Pierre Louis Maupertuis. Celsius founded the Uppsala Astronomical Observatory in 1741, and in 1742 he proposed the Celsius temperature scale in a paper to the Royal Swedish Academy of Sciences.

Anders Celsius (1701-1744) was a Swedish astronomy professor and physicist, perhaps most famous for his temperature scale. He was ... a writer of poetry and popular science. One of the major questions in that time was what shape the Earth had. Newton et al had proposed that the Earth was not completely spheric, but rather flattened at the poles. Cartographic measuring in France suggested that it was the other way around: the Earth was elongated at the poles. In 1735, one expedition sailed to Ecuador in South America, and another expedition, led by Pierre Loius Moreau de Maupertuis, to Torneå in northern Sweden.

Anders Celsius, born in Uppsala, was one of a large number of scientists (all related) originating from Ovanåker in the province of Hälsingland. The family name is a latinised version of the name of the vicarage (Högen). His grandfathers were both professors in Uppsala: Magnus Celsius the mathematician and Anders Spole the astronomer. His father, Nils Celsius, was ... professor in astronomy. Celsius, who was said to have been very talented in mathematics from an early age, was appointed professor of astronomy in 1730.

While professor of astronomy at the Univ. of Uppsala (1730–44), he traveled through Germany, France, and Italy, visiting great observatories. At Nuremberg in 1733 he published a collection of 316 observations of the aurora borealis made by himself and others. While in Paris he was instrumental in bringing about an expedition (of which he became a member) organized by the French Academy for the measurement of an arc of the meridian in Lapland (1736). He supervised the building of an observatory at Uppsala in 1740 and became its director; while there he pioneered in the measuring of the magnitude of stars, using photometric methods. In 1742 he invented the centigrade (or Celsius) thermometer.

Anders Celsius was born at the 27th of January 1701 in Uppsala. After his education time in this town north of Stockholm he became professor for astronomy already in 1730. At this time there was no larger observatory anywhere in Sweden. Therefor Celsius began a round trip to some of the famous European astronomy sites in 1732. He came from Nuremberg and Rome to Paris in 1734.

Anders Celsius was born in Uppsala on the 27th of November in 1701 and died there on the 25th of April in 1744. He was an astronomer and became professor at Uppsala University in 1730. He published widely, among others ‘Observations on the Northern Lights in Sweden’ in 1733. Anders Celsius principally gained his reputation by introducing a thermometer of 100 degrees.
