Parts of Cell Theory
~Everything living is composed of other cells.
~Cells come from other cells.
~The cell is the smallest basic unit of life.
Robert Hooke (1635-1703)
Robert Hooke looked through a piece of cork and drew what he saw. What he drew had reminded him of the cells in a monastery. In the year 1653 he had created the cell. When he was 26 he took the assignment from Wren and then joined the Royal Society for Scientists. Hooke then published his drawing in 1665.
Anton Van Leeuwenhoek (1632-1723)
Leeuwenhoek took up similar work as Robert Hooke. In the 1670's he looked at a drop of pond water and realized that there is tons of living organisms .
Theodor Schwann (1810-1882)
In 1836 Schwann discovered the digestive enzyme pepsin. He should that yeast were tiny plant-like organisms. 1839 he then extended Schleiden's cell theory to a animals , stating that all living organisms are composed of cells.
Mathias Schleiden(1804-1881)
Mathias was the cofounder with Theodor Schwann of the cell theory. He educated at Heidelberg (1824-1827) and practiced law. Scheilden preferred to study plant structure under a microscope.
Rudolf Virchow(1821-1902)
Virchow became a licensed doctor in 1846. In 1847 he became an instructor at University of Berlin. He did research at Wurzburg and helped establish the concept of cellular pathology, idea that all diseases are caused by changes in normal cells.
