General Microbiology, History Francesco Redi (1626-1697) By Famous Scientists, an educational resource focusing on the lives and achievements of the most famous scientists and inventors in history. When microorganisms were known to exist, most scientists believed that such simple life forms could surely arise through spontaneous generation. 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. The History of Italian Parasitology Anton van Leeuwenhoek is often credited as being the inventor of the microscope, but that is not actually the case. Washington, D.C.: ASM Press.

He disproved the theory of spontaneous generation of disease and postulated the germ theory of disease. In 1668, in one of the first examples of a biological experiment with proper controls, Redi set up a series of flasks containing different meats, half of the flasks sealed, half open.

Modern cell theory isn't all that modern when you understand how long ago it originated. He covered three jars with gauze, and he left the other three open. Barbara McClintock: She described transposons.10. Because the meat was covered, no maggots were produced, and this led Francesco Redi to drop the notion of spontaneous generation. He also found that fermentation of fruits and grains, resulting in alcohol, was brought about by microbes and also determined that bacteria were responsible for the spoilage of wine during fermentation.
