Aristotle
Creater of Histroy of Animals. Also, Aristotle was a tutor fir Alexander the Great back in 338. Aristotle was for spontaneous generation because he said animals of some kinds arise directly from elements and the pneuma of the material. -
Zacharias Janssen
Invented the first microscope in the year 1590. Janssen's invention rejects the idea of spontaneous generation. It rejects spontaneous generation because the microscope shows living orangisms and cells. www.history-of-the-microscope.org -
Jan Baptist van Helmont
In 1620 Jan, a physiologist and physician, discovered the concept of gas. That gas was known as carbon dioxide. Helmont accepted the idea of spontaneous generation but said knowledge of the world can only be tested by experimentation. -
Robert Hooke
Robert Hooke was the first person to use the word "cell" to identify microscopic structures in 1665. He rejects spontaneous generation because scientists looked at cells of different things. www.ucmp.berkelely.edu -
Anton van Leeuwenhoek
Anton is famous for discovering "protozoa". Protozoa is a single celled organism and he clled them "animalcules". Leeuwenhoek also improved the microscope and is often cited as the first microbiologist to study muscle fibers, bacteria, spermatozoa, and blood flow in capillaries. He aslo was first to see and describe bacteria in 1674. Anton rejects spontaneous generation because while observing organisms, he noticed they reproduced through
procretation just as larger organisms did. -
Lorenz Oken
Created the Sea Slime Theory and discovered philosophy of nature in the year 1809. He was a German naturalist, botanist, biologist and ornithologist. He supported the sponyaneous generation thought because he thought that where land and sea meet, in one minute bladders of foam enclosed 3 life principles; feeding, respiration and digestion. That was his believe on how it happened. www.talkorigin.org -
Robert Brown
Robert Brown discovered the cell nucleus. Robert Brown rejectcs spontaneous generation because the cell nucleus controls everthing the cell does and that means the reproduction processs and Brown knew that. -
Matthias Schleiden
created cell theory with Theodor Schwann in 1839. The cell theory indicates that all living things are made up of one or more cells. This discover rejects spontaneous generation because the cell theory basically supports the idea of "parent cells" while spontaneous generation doesn't come from other cells.

Theodor Schwann
A german physiologist who developed one major thing, cell theory. Schwann aslo invented the term metabolism, organic nature yeast, pepsin, and the cells in periplural nervus sysyem. Theodors invention rejects the belief of spotnanoeus generation because the cell theory indicates that things come from "parehnt cells" and don't just show up. www.famousscientists.org -
Alberecht von Roelliker
Roelliker was the first to realize that sperm cells and egg cells were aslo cells in 1840 and he was against spontaneous generation becuase he realized you need sperm and egg cells for it and oragnisms have those two things. -
Rudolf Virchow
Virchow's most famous observation was that a whole organism does not get sick, only certain cells or groups of cells. Also, he said all diseases involve changes in normal cells, that is, all pathology ultimately is cellular pathology. His discovery led to major progress in practice of medicine, deisease entities and were defined more sharply. Rudolf was against spontaneous generation because he showed that the origins of cells was the division of preexisting cells. -
Louis Pasteur
Created an expirement that determined that food or soup exposed to air only spoiled if the air wasn't filtered or if the flask had an opening that allowed microscopic organisms to get inthe S-shaped necks were micro organisms got stuck and didn't spoil the soup in 1864. Also, Louis rejected spontaneous generation and stated that life comes from life not from dust. www.talkorigin.org
