Key Facts & Information
EARLY LIFE AND FAMILY
- Born in Uppsala, Sweden on November 27, 1701, Anders Celsius was the son of Nils Celsius, an astronomy professor, and the grandson of two professors in Uppsala – Magnus Celsius, a mathematician, and Anders Sole, an astronomer.
- His surname came from the Latin word “Doma”, their family’s estate. They were from Ovanåker in Hälsingland, a historical province of Sweden.
EDUCATION
- Known to be very talented in mathematics, he finished his education in his hometown, north of Stockholm.
- He earned his degree at Uppsala University.
CAREER BEGINNINGS
- In 1723, Celsius became the secretary of the Uppsala Scientific Society. This was located at the same university his father taught at.
- Seven years later, he became a professor of astronomy at Uppsala. He also started traveling to study and collaborate with other astronomers across Europe. He retired from teaching at Uppsala in 1744.
AS AN ASTRONOMIST
- From 1716 to 1732, together with some scientists, he studied the Aurora Borealis, commonly known as the Northern Lights.
- On December 5, 1733, Celsius published his collections of 316 observations on the Northern Lights. These documents were submitted to the Royal Society of Sciences in Uppsala.
- He presided over 20 research projects in astronomy, and even wrote a book, “Arithmetics for the Swedish Youth”.
- His other works include “A Dissertation on a New Method of Determining the Distance of the Sun from the Earth” (Dissertatio de Nova Methodo Distantiam Solis a Terra Determinandi), written in 1730, and “Disquisition on Observations Made in France for Determining the Shape of the Earth” (De Observationibus pro Figura Telluris Determinanda in Gallia Habitis, Disquisitio) in 1738.
- Celsius took measurements that proved Newton’s theory about the shape of the earth – it was an oblate spheroid rather than a sphere. December 3, 1736, marked his first major scientific success.
- In 1740, he built the Uppsala Observatory, Sweden’s first.
AS A PHYSICIST AND MATHEMATICIAN
- In 1742, he invented the Celsius (Centigrade) scale for his meteorological observations. This is a mercury thermometer at an air pressure of 760 mm, with 100 divisions and calibrated at 0 degrees for boiling point and 100 degrees for freezing point.
- The name of his scale was originally Centigrade, a Latin word meaning “hundred steps”.
HONORS
- In 1725, Celsius became the secretary of the Royal Society of Sciences in Uppsala.
- In 1745, a year after his death from tuberculosis, Carl Linnaeus reversed his scale in order to facilitate more practical measurements with the aid of negative numbers. Thus, 0 degrees became freezing point.
- “Degree Celsius”, the unit of temperature interval, was named after him in 1948.
- He was also known for his advocacy of the Gregorian calendar, adopted nine years after his death.
