Timeline of Microscopes and The Cell Theory

  • Micrographia

    Robert Hooke published "Microgphia". It had illustrations of objects drawn with the help of his microscope. First to use the tern "Cell" when describing a cork.
  • Important Discoveries in Biology

    Important Discoveries in Biology
    Antony van Leeuwenhoek discovered bacteria, free-living and parasitic miscroscopic protists, sperm cells, blood cells and more with his microscope that could magnify up too 300X.
  • Achromatic Lenses

    Achromatic Lenses
    Achromatic lenses can provide resolution of 1 micron.

    The Cell Theory Was Started
    Theodor Schwann and Matthias Schleiden formally proposed the "Cell Theory".
  • Micrographs

    Donne published the first micrographs in France.
  • Theory of the Microscope

    Theory of the Microscope
    Ernst Abbe published his work on the theory of microscope. His formula to caculate resolution is based on his wave light theory.
  • Revolving Turret

    Revolving Turret
    Ernst Leitz introduced a revolving turret for 5 objectives.
