The History of the Microscope and Cell Theory

  • Microscope is Invented

    Microscope is Invented
    A father- son team, Hans and Zacharias Jansen, create the first microscope.
  • Period: to

    Relationship Through Time of the Invention of the Microscope and the Discovery of Cell Theory

  • Cell

    Robert Hooke discovers the cell. He publishes his work two years later.
  • Microgphia is Published

    Microgphia is Published
    Robert Hooke publishes "Microgphia, a folio of 38 sketches that he drew with the aid of his microscope. Hooke becomes to coin phrase the word cell while study a piece of cork.
  • Leeuwenhoek Discovers Multiple Types of Cells

    Leeuwenhoek Discovers Multiple Types of Cells
    Antony van Leeuwenhoek made the incredibly important biology discoveries of bacteria, free living and parasitic microscopic protist, sperm cells, blood cells, and many more.
  • "Little Animals"

    Antoni van Leeuwenhoek discovers " little animals"- bacteria and protozoain samples through his microscope.
  • Cell Nucleus

    Cell Nucleus
    Leeuwenhoek describes the cell nucleus in his findings.
  • Microscope Lenses Improve

    Achromatic lenses are introduced to provide a resolution of 1 micron.
  • Nucleus is Confirmed

    Nucleus is Confirmed
    Robert Brown names the cell nucleus and suggests its importance in fertilization.
  • Cell Theory is Proposed

    Theodor Schwann and Matthias Schleiden formally propose "Cell Theory".
  • First Statement of Cell Theory

    "Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals" is published by Theodor Schwann, Includes the first statement of cell theory: All living things are made up of cells.
  • Micrographs are Invented

    Micrographs are Invented
    Donne' publishes the first micrographs in France.
  • Division of a Cell

    Division of a Cell
    Robert Remak developes a method to isolate the cell membrane and proves it divides a cell.
  • Pathology

    Rudolf Virchow endorses cell division and its role in pathology.
  • Theory of the Microscope is Published

    Ernest Abbe work on the theory of the microscope making a clear difference between magnification and resolution. His formula on how to calculate resolution based on his wave light theory becomes widely spread.
  • Revovling Mount

    Ernest Laitz introduces a turret for microscopes a revolving mount for 5 different objects.
  • Mitosis

    Walther Flemming discovers mitosis.
  • Microscope Quality Improves

    August Kohler added a microscope lamp with filters that allows a clearier quality image.
  • Microtromes

    Microtromes appear for sample preparation.
  • Apochromatic Design

    Ernest Abbe designs apochromatic object allow blue, yellow, and red to focus into one. This can only be used with 10 or more elements.
  • UV Microscope

    UV Microscope
    First commerical UV microscope by Zeiss is invented. The resolution is twice that of a visible light microscope.
