  • Period: 1500 to 1514

    Copernicus

  • Period: to

    Johan Becker

  • Period: to

    Paracelsus

    Believed everything was mad of salt, sulfur and mercury.
  • Period: to

    Robert Boyle

    Wanted to investigate and experiment on phosphorus and shared his methods which helped expand the mysteries in matter
  • Period: to

    Joseph Priestly

    First salaried chemist to perform one of the most impactful experiments in the world which led to the discovery of oxygen.
  • Period: to

    Henry Cavendish

    Collected gas derived by Zinc dissolved by acid discovering Hydrogen.
  • Period: to

    Hennig Brand

    Believed gold could be found within humans but discovered phosphorus instead
  • Period: to

  • Period: to

    Humphry Davy

    Discovered Potassium
  • Period: to

    Dmitri Mendeleer

    Left empty spots in periodic table and made predictions on the missing elements and had a astounding grasp of chemistry. He also discovered radium to which his findings had to be altered to which he did not want to believe.
