Olof Celsius's father was the mathematician Magnus Celsius and his nephew Anders Celsius (son of his brother and astronomy professor Nils Celsius) was an astronomer who invented a temperature scale where 100 originally represented the freezing point of water and 0 represented the boiling point.
From the scientific point of view the most important contribution to the modern temperature scale is due to Celsius because of his careful experiments on the fixed points. The direction of the scale comes in second place, and was hardly a great intellectual achievement. Olof Beckman. - Biography.

Anders Celsius was born in Upsala, Sweden, the son of an astronomy professor from a noble family from Doma Estate in Ovanåker. He completed his education near Stockholm. Early, his talents in mathematics were noticed and Celsius enrolled at Uppsala University, where he (following his father’s footsteps) was appointed professor of astronomy in 1730....
It is assumed that Celsius’ interest in general problems of weights and measures evolved early. Back in his time as a student, he was the assistant to the astronomy professor Erik Burman and engaged in meteorology observations. However, a pretty large variety of different thermometers existed and it is assumed that Celsius already saw the need for ...
It is assumed that Linné ordered his famous mercury thermometer around 1743 and Ekström was able to deliver it in 1744, the year of Anders Celsius’ death. The first thermometer was broken during the delivery and it took another year to arrive at the garden of Linné. He demonstrated it to the Board of the University of Uppsala with great success. It...
However, the most important contribution to this field of science and to the modern temperature scale is due to Anders Celsius, because of his accurate and careful experiments on fixed points. In 1741 he completed the first Swedish observatory in Uppsala. He was also a poet and author of popular science literature. Celsius was the first to measure ...
In 1948, about 200 years after the scale was introduced, the 9th International General Conference on Weights and Measures officially renamed the scale interval for a Celsius thermometer from one centigrade or centesimal degree to the temperature unit degree Celsius in honor of Celsius. The original thermometer can be seen today in Uppsala Universit...
For his metereological observations he constructed his world famous Celsius thermometer, with 0 for the boiling point of water and 100 for the freezing point. After his death in 1744 the scale was reversed to its present form.
Nov 27, 2016 · Originally, Celsius placed the boiling point at 0 and the freezing point at 100, but upon Celsius’ death in 1744, the noted taxonomist Carolus Linnaeus proposed reversing the scale. The result was the more intuitive modern version of the Celsius scale, where 0 is the freezing point of water.
Anders Celsius and the fixed points of the Celsius scale - NASA/ADS. Beckman, Olof. In the middle of the 18th century around 30 different temperature scales with various fixed points existed, but only the scales by Fahrenheit, Réaumur and Celsius have survived to the present time.
Doctor Olof Celsius (1670-1756) created one of the oldest herbarium collections at the Swedish Museum of Natural History, his Flora Upplandica from 1730. Dr. Olof Celsius was the uncle of Professor Anders Celsius (1701~1744), the man who developed the modern system of temperature measurement.
