Francesco Redi was born on February 18, 1626 in the city of Arezzo in Tuscany, Italy. 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. Eukarya, which includes the following: Protists (slime molds, protozoa, and algae) Fungi (unicellular yeasts, multicellular molds, and mushrooms) Redi was a contemporary of Galileo, who faced opposition from the Church. Experimental science was in its infancy, and Redi came up with a brilliant new idea: the controlled experiment. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. Until about the 1880s, people still believed that life could form out of thin air and that sickness was caused by sins or bad odors. He developed techniques to stain tissues and blood cells.

Who is Francesco Redi and what did he discover? How did Redis work impact the field of toxicology? The experiments with maggots and flies were important not only because they refuted spontaneous generation, but also because they used control groups, applying the scientific method to test a hypothesis. As will happen with any food source left sitting around, it became moldy, growing a patch of fuzzy fungus. Jenners experimental significance was realized by Pasteur who next applied this principle to the prevention of anthrax and it worked. Spontaneous generation, the theory that life forms can be generated from inanimate objects, had been around since at least the time of Aristotle. Redi taught the Tuscan language, supported the writing of a Tuscan dictionary, was a member of literary societies, and published other works. The first serious attack on the idea of spontaneous generation was made in 1668 by Francesco Redi, an Italian physician and poet. Galileos viewpoint sounded so appropriate that Redi applied it in his own investigations. 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 observations backed up his conviction that parasites laid eggs from which offspring developed and did not grow spontaneously. Redi believed that maggots developed from eggs laid by flies. A little over a decade later, Antonie van Leeuwenhoek confirmed Redis maggot and fly work, observing the entire lifecycle. Finally, in 1862, Louis Pasteur completely killed off the idea of spontaneous generation in mainstream science. At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. Burtons microbiology for the health sciences.

In addition to his refutation of spontaneous generation, Experiments on the Generation of Insects contained Redis detailed drawings of a large variety of insects, eggs, and maggots, such as these below. Virchow used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular level. A chronology of events and pioneers of microbiology. Redi is famous for his controlled experiments and has contributed to microbiology by disproving the 'spontaneous generation theory'.
