History of the cell theory

By, Garrett Orrell

Robert Hooke, Anton van Leeuwenhoek, Theador Schwann, Matthias schleiden, and Rudolph Virchow

  • Robert Hooke was an English physicist who discovered the law of elasticity, on January 01, 1653 he discovered the cell.
  • Anton van Leeuwenhoek was a Dutch tradesmen and scientist, he was the first to find and describe single celled organism.
  • 1839: Theodor Schwann, a German biologist, reached the same conclusion as Schleiden about animal tissue being composed of cells, ending speculations that plants and animals were fundamentally different instructure. Schwann described cellular strucures in animal cartilage (rigid extracellular matrix).
  • 1855: Taking Brown's original description of nuclei and observations by Karl Nägeli on cell division, the German physiologist, physician, pathologist, and anthropologist Rudolf Virchow was able to add a third tenet to the cell theory: Omnis cellula e cellula, or all cells develop only from existing cells.Virchow, Rudolf (1821-1902), German pathologist, archaeologist, and anthropologist, the founder of cellularpathology. Virchow was born in Schivelbein, Pomerania (now Swidwin, Poland), and educated at theUniversity of Berlin.
  • 1838: Matthias Jakob Schleiden, a German botanist, concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter. This statement of Schleiden was the first generalizations concerning cells.
