A Biological Timeline

  • Hans and Zacharias Janssen

    Hans and Zacharias Janssen
    were dutch specticale makers who were first to invent the first compound microscope.
  • Antoni van Leeuwenhoek

    Antoni van Leeuwenhoek
    He is commonly known as the "father of microbiology" and is considered to be the first microbiologist. He is best known for the work he did on the microscope. He contributed to spontanious generation by revolutinising the microscope there for leading to a better understanding of cells.
  • Robert Hooke

    Robert Hooke
    Robert Hooke contributed to the theory of scientific revolution by createing the term cell which is the basic life form all liveing things are made of. he is best know as "the father of microscopy"
  • Francesco Redi

    Francesco Redi
    he is best known for his expariments which contributed to spontanious generation. the main thing he found out was that liveing organisms dont evolve from the air.
  • Lazzaro Spallanzani

    Lazzaro Spallanzani
    He was a catholic who researched the theory of spontanious generation. His expariment proved that microbes move through the air and can be killed through boiling.
  • John Needham

    John Needham
    He suggested that there was a "life fource" in the air that created misterious organisms.
  • Robert Brown

    Robert Brown
    Robert Brown contributed to spontanious generation by conducting an expariment where he rulled oout the theory of non liveing things being alive. That is known of the Brownian Motion
  • Theodor Schwann

    Theodor Schwann
    Was a german Zoologist His many contributions to biology include the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism.
  • Louis Pasteur

    Louis Pasteur
    He was a french chemist and a microbiologist. Louis Pasteur greatly contributed to spontanious generation by createing the "germ theory" he proformed a series of expariments leading to the findings of the cures for deiseses such as peupular fever and rabies.
  • Matthias Jakob Schleiden

    Matthias Jakob Schleiden
    was a german biologist ho was a co-founder of the cell theory.
  • Rudolf Virchow

    Rudolf Virchow
    was a public health actavist, piologist, biologist and a polotician he created the "cell theory" which means that every liveing organism comes from another liveing organism and not an unknown "life fource".
  • Cell theory

    Cell theory
    Cell theory refers to the idea that cells are the basic unit of structure in every living thing. Development of this theory during the mid 1600s was made possible by advances in microscopy. This theory is one of the foundations of biology. The theory says that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all living organisms.
