Anders Celsius independent of latitude (and of atmospheric pressure). He determined the dependence of the boiling of water with atmospheric pressure which was accurate even by modern-day standards. He further gave a rule for the determination of the boiling point if the barometric pressure deviates from a certain standard pressure. 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 100° for the freezing point of water and 0° for the boiling point. In 1745, a year after Celsius'
Anders Sandøe Ørsted Sandøe Ørsted (1816–1872). Anders Sandøe Ørsted Anders Sandøe Ørsted (21 December 1778, Rudkøbing – 1 May 1860) was a Danish lawyer, politician and jurist. He served as the Prime Minister of Denmark in 1853–1854. He studied philosophy and law at Copenhagen and was admitted to the bar in 1799. He became a noted jurist. An early case overseen by him was that of Hans Jonatan, an escaped slave, which was (at least viewed retrospectively) a major test case in Danish law on slavery; Anders condemned Hans to be returned to the West Indies, where he had been purchased (Hof-og Stadsret:
