Question: Where do the flies come from? 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. He documented his observations in his 1684 book Observations on living animals that are in living animals. He compared the health outcomes for animals given chemical treatments for their parasites versus animals kept under the same conditions but given no treatment for their parasites. He has many contributions to microbiology: Principles of fermentation Pasteurization of milk Sterilization techniques The germ theory of disease. Redi devised and performed the now-famous experiment in which six jars, half left in open air and half covered with fine gauze that permitted air circulation but kept out flies, were filled with either an unknown object, a dead fish, or raw veal. 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. .
