Spontaneous generation, the theory that life forms can be generated from inanimate objects, had been around since at least the time of Aristotle. His work led to the development of the germ theory of disease. At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. What contribution did Virchow make to the cell theory? Because the meat was covered, no maggots were produced, and this led Francesco Redi to drop the notion of spontaneous generation. History of Microbiology | Biology Quiz - Quizizz He read in the book on generation by William Harvey a speculation that vermin such as insects, worms, and frogs do not arise spontaneously, as was then commonly believed, but from seeds or eggs too small to be seen.

Finally, in 1862, Louis Pasteur completely killed off the idea of spontaneous generation in mainstream science. He observed that flies laid eggs on meat. He described his work in 1668 in Experiments on the Generation of Insects. Antonie van Leeuwenhoek (1632-1723) was one of the first people to observe microorganisms, using a microscope of his own design, and made one of the most important contributions to biology.
