Redi is known as a poet chiefly for his Bacco in Toscana (1685; Bacchus in Tuscany). He attended St. Xaviers College, Maitighar, Kathmandu, Nepal, to complete his Master of Science in Microbiology. The fish and veal rotted in both groups, but maggots only formed in the jars open to air. Pasteur, thus in 1858 finally resolved the controversy of spontaneous generation versus biogenesis and proved that microorganisms are not spontaneously generated from inanimate matter but arise from other microorganisms. In 1668, Francesco Redi, an Italian physician, did an experiment with flies and wide-mouth jars containing meat. It also explained the origin of life from the nonliving subjects. Francesco Redi, (born Feb. 18, 1626, Arezzo, Italydied March 1, 1697, Pisa), Italian physician and poet who demonstrated that the presence of maggots in putrefying meat does not result from spontaneous generation but from eggs laid on the meat by flies. One of Redis most famous experiments investigated spontaneous generation. Redi's poem "Bacchus in Tuscany" was published after his death. Redi has been called the "father of modern parasitology" and the "founder of experimental biology". Louis Pasteur is known as the Father of Modern Microbiology / Father of Bacteriology. Until this point, research was focused mainly on plant and animal cells, which are much more complex than bacterial cells. In the experiment Redi prepared three groups of jars, each with a pieces of meat inside them. In 1837, Italian zoologist Filippo de Filippi named the larval stage of the parasitic fluke "redia" in honor of Redi. What did Francesco Redi observe in living animals? Redi documented over 100 parasite species, observing once again that creatures popularly believed to generate spontaneously actually hatched from eggs. What was Francesco Redi contribution to microbiology? Spontaneous generation theory is an archaic scientific theory which stated that living organisms could arise from nonliving matter and that such a process was regular in nature.

For example, in reference to his work on spontaneous generation, Redi concludedomne vivum ex vivo("All life comes from life"). His scientific work resulted in a number of significant milestones: he showed that flies breed and lay eggs and do not, as was popularly believed, spontaneously generate; his microscopic examination of parasites marked the founding of modern parasitology; and in studying chemical treatments to kill parasites, he devised and performed the first controlled experiments in scientific history. Leeuwenhoek made microscopes consisting of a single high-quality lens of very short focal length.

Redi performed series of experiments in the early 1670s in which he covered jars of meat with fine lace that prevented the entry of flies into the jars. At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. This is called abiogenesis. 2. He was buried in his hometown of Arezzo. Ehrlich received the Nobel Prize in Physiology or Medicine in 1908. The compound found to be responsible for this antibacterial action was named penicillin. He then repeated the experiment but, instead of sealing the flasks, covered half of them with gauze so that air could enter.
