  boiling water he had 180 degrees on his
  scale.
  Anders Celsius

  was not popular with the church at the time
  because he suggested that it was a continual
  process and did not have a beginning.

  patients with magnets and some got
  better. Later he stopped using magnets
  and waved his hands over the patients he
  called this animal magnetism.
 Joseph Lagrange



• He came up with the metric system.
• Born AD 1736 Died 1813.

  publish. Amongst the chemicals he is
  accredited with are Manganese, Tungsten,
  Chlorine and Nitrogen.

  because the French revolution occurred.
 Antoine Lavoisier


• The father of modern chemistry.
• Born AD 1743 Died 1794.
• He did not discover oxygen but he did

  combustion. All of his experiments were
  carefully measured and recorded clearly.
  He died on the guillotine because they
  said there was no need for chemist in the
  French revolution.
  Joseph Banks
• Plant specialist.
