Cell Theory Timeline

  • Anton van Leeuwenhoek October 24, 1632

    Anton van Leeuwenhoek October 24, 1632
    He was also the first to record and observe muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels)
    Using handcrafted microscopes, Anton was the first person to observe and describe single celled organisms which he originally referred to as animalcules.
    Anton discovered the organisms unlike Hooke who saw the cell walls in the tissue. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
  • Robert Hooke January 1st, 1665

    Robert Hooke January 1st, 1665
    His most famous observation was in his study of thin slices of cork, describing "cells" he viewed. Hooke discovered plant cells by viewing the cell walls in cork tissue. He discovered a honeycomb-like structure in a cork slice. He only saw cell walls as this was dead tissue. He coined the term "cell" for these individual compartments he saw.
    No one had made this discovery about cells before. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
  • Robert Brown 1833

    Robert Brown 1833
    Robert Brown, an English botanist, discovered the nucleus in plant cells. He discovered more about the cell than Leeuwenhoek or Hooke. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
  • Matthias Schleiden 1838

    Matthias Schleiden 1838
    Was a German botanist and co-founder of the cell theory, along with Theodor Schwann and Rudolf Virchow.
    He proposed that all plant tissues are composed of cells, and that cells are the basic building blocks of all plants. This statement was the first generalized statement about cells.
    Schleiden has gone deeper than any other scientists because he discovered that cells are the building blocks of the all plants. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
  • Theodor Swhann 1839

    Theodor Swhann 1839
    Schwann proposed three generalizations concerning the nature of cells: animals and plants consist of cells plus the secretions of cells. These cells have independent lives, which, are subject to the organism's life. He also stated: Cells are organisms and all organisms consist of one or more cells,The cell is the basic unit of structure for all organisms.
    He was the first person ever to come up with the nature of cells. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
  • Rudolf Virchow 1855

    Rudolf Virchow 1855
    He proposed that all cells result from the division of previously existing cells, and this idea became a key piece of modern cell theory.
    Virchow also founded the discipline of cellular pathology based on the idea that diseases do not affect an entire organism but are instead localized to certain groups of cells.
    Even though other scientists knew about cells Virchow was the first to discover the pre-existing cells. "Sweet Search." Sweet Search. N.p., n.d. Web. 06 Oct. 2016.
