Celsius, Anders [Astro*Index]

(1701-1744) Swedish astronomer.

Born and died at Uppsala. Professor of astronomy at Uppsala, he was first to use a device (other than the human eye) to determine the magnitude of stars. He is best known for the temperature scale which he devised, which placed the freezing point of water at 0°, and its boiling point at 100°. Long called the Centigrade scale, in 1948, scientists agreed to call it the Celsius scale. The accepted scale among scientists, this scale replaced the older Fahrenheit scale, although the latter is still found in use for non-scientific applications in some countries.
