    Leeuwenhoek was able to see what he called animalcules, due to its characteristics. He also noticed bacteria and observed it, some years later he also observed protozoa and bacteria.
  • Matthias Schleiden Contributes to Cell Theory

    Matthias Schleiden Contributes to Cell Theory
    Matthias was one of the so-called founding fathers for the cell theory, he showed that all development of tissues also came from cells. Later, more scientists would add to the cell theory.
  • Schwann Also Contributes To Cell Theory

    Schwann Also Contributes To Cell Theory
    Schwann founded histology by stating the cell as the basic unit of animal structure. He also helped with what would be known today as the cell theory. He also posted a journal in 1839 called, Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants. He extended to animals the cell theory in the book.
  • Rudolf Virchow Contributes

    Rudolf Virchow Contributes
    Virchow was one to state that disease doesn't happen in organs and tissues, but he stated that it happened in the individual cells, giving people more knowledge on cells. He also would add to the cell theory and he gave multiple lectures on cells and more.
