  • First Microscope

    First Microscope
    Two Dutch eye glass producers, Zaccharias Janssen and his son Hans, experimented with all different types of lenses put in a tube. They put objets infron of the tube lense and saw that they were larger, creating thenforerunner microscope , the compund microscope, and the telescope.

  • Robet Hooke

    Robet Hooke
    Discovered cells and came up with the term "cell".

  • Antony Van Leeuwenhoek

    Antony Van Leeuwenhoek
    Made sample micorscopes and started observing

  • First Microscope

    First Microscope
    Anton Von Leewenkoek made a simple microscope with jsut one lens, he could see tiny objects such as insects, bloodm and yeast. Leewenhoek came up with new methods for grinding and polishing microscopes, allowing magnification up to 270 in diameters.

  • Schwan

    Schwan
    Discovered digestive enzyme.

  • Cell Theory

    Cell Theory
    Cell Theory was inventev by Schleiden and Schwan. The Cell Theory states:
    - "All living organisms are composed of cells. They may be unicellular or multicellular"
    -"The cell is the basic unit of life"
    - "Cells arise from pre-existing cells"

  • Schledin

    Schledin
    Schledien and Schwan invented the cell theory. Schwan told Shledien about plant cells with nuclei, he was shocked when he thought about the similarity between the plant cell and animal cell.

  • Schwan

    Schwan
    Added on to the cell theory, "All living things are composed of cells".

  • Rudolf Virchow

    Rudolf Virchow
    With the support of Froriep, he becamse a professor in 1847.

  • Schleiden

    Schleiden
    Finally,he became an Appointed Professor of Natural Science's.

  • Rudolf Virchow

    Rudolf Virchow
    His part in contributing to the cell theory gives detail on the effects of disease on the body.

  • Electron Microscope

    Electron Microscope
    Ernst Ruska co-invented the Elecrton Microscope. An Elecrton mcroscope relys on electrons instead of light to look at an object. Electrons are raced up in a vacuum until their wavelength is awfully short, only one hundred thousand of white light. These microscopes are able to see very small things, even as small as the diameter of an atom.
