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'
David Kennedy (astronomer) he was the provincial superior of the Society of Mary in New Zealand. He died in Wellington on 10 March 1936. David Kennedy (astronomer) David Kennedy (27 April 1864 – 10 March 1936) was born at Lyttelton, New Zealand, the son of an Irish mother and a Scottish father who came to New Zealand from Melbourne in 1863. He became the first New Zealand born priest of the Society of Mary (Marists), a noted astronomer and educator. As a boy he showed a keen interest in both theology and science.
