    Robert Hooke discovers Hooke's Law and uses cell to identify microscopic structures
    Looked at a sliver of cork through a microscope lens and noticed some pores in the cork or now cells. He thought these cells existed only in plants, Hooke was the first person to use the word cell to identify these microscopic structures when he described cork. He also wrote Hooke's Law -- a law of elasticity for solid bodies.

  • Albercht von Roelliker discovered many things from red blood cells to evolution

    Albercht von Roelliker discovered many things from red blood cells to evolution
    Kölliker’s investigations covered such diverse subjects as the development of cephalopods (e.g., octopus, squid), the structure of smooth muscle, the development and differentiation of red blood cells, and the significance of the germ layers in development. He described spermatozoa as cellular in origin and nature and emphasized the significance of sudden change in evolution as opposed to gradual change.

    Louis Pastreur discovers fermenation of cells
    He was one of the most important founders of medical microbiology. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization; saved the beer, wine, and silk industries in France; and developed vaccines against anthrax and rabies.Pasteur’s studies of butyric acid fermentation. These studies led Pasteur to the unexpected discovery that the fermentation process.
