  • German chemist Andreas Marggraf

    realizes that alum (a natural aluminum compound used for dying textiles since ancient times) contains an unknown metal. It's aluminum,but he doesn't know that.
  • Danish chemist and electrical pioneer Hans Christi

    turns aluminum oxide into aluminum chloride and then uses potassium to turn the chloride into pure aluminum. Unfortunately, he cannot repeat the trick a second time!
  • French chemist Henri Sainte-Claire Deville

    uses sodium to separate out aluminum. Since sodium is cheaper and easier to obtain than potassium. He puts this on display at a public exhibition in Paris, France. Deville's new method means aluminum starts to become more widely available and the price begins to fall.
  • Charles Martin Hall nd his sister Julia Brainerd Hall and Frenchman Paul-Louis-Toussaint Héroult

    discover the modern method of splitting aluminum oxide with electrolysis to make pure aluminum. Their highly efficient technique, known as the Hall-Héroult process, is still used to produce most of the world's aluminum today.
  • Austrian chemist Karl Bayer

    finds a less expensive way of turning bauxite into aluminum oxide—the raw material needed for the Hall-Héroult process. Together, the Bayer and Hall-Héroult processes drastically reduce the price of aluminum, enabling the metal to be used in much greater quantities.
  • Aluminum

  • Modern aluminum alloys begin to appear

  • American Chemical Society

    officially changes the name from "aluminium" to "aluminum" in the United States.
