Redi gained fame for his controlled experiments. Francesco Redi's main contribution to biology was proving that maggots did not erupt spontaneously from rotting meat, but were deposited there in the eggs of flies. The Greek philosopher Aristotle (384-322 BC) was one of the earliest recorded scholars to articulate the theory of spontaneous generation, the notion that life can arise from nonliving matter. In the experiment Redi prepared three groups of jars, each with a pieces of meat inside them. Please refer to the appropriate style manual or other sources if you have any questions. He demonstrated that it is not true that vipers drink wine, that swallowing snake venom is toxic, or that venom is made in a snake's gallbladder. 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 used solid media for the culture of bacteria-Eilshemius Hesse, the wife of Walther Hesse, one of Kochs assistants had suggested the use of agar as a solidifying agent.

The Tuscan Redi (18 February 1626 - 1 March 1697), chief physician at the court of the Medici, had no lack of academic paternities: in various reference sources he is designated as the father of experimental biology, parasitology, experimental toxicology and helminthology (the study of helminth worms).

Sometimes, this bacteria is called the "Weizmann organism" after the name of Chaim Weizmann.

Having observed the development of maggots and flies on decaying meat, Redi in 1668 devised a number of experiments, all pointing to the same conclusion: if flies are excluded from rotten meat, maggots do not develop. First experiments and contributions. Francesco Redi, as far back as 1668, had set out to refute the idea of macroscopic spontaneous generation, by publishing the results of his experimentation on the matter. Spallanzani was largely criticised under claims that microorganisms needed oxygen to survive. Summers W.C (2000).

Besides Galileo, he was one of the most important scientists who challenged Aristotle 's traditional study of science. Foundations in Microbiology. 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. Francesco Redisuccessfully challenged and refuted the theory of spontaneous generation through his work on maggot and flies, in which he showed that maggots on meat came from egg flies.

Bacchus in Tuscany He described his work in 1668 in Experiments on the Generation of Insects. The organism must be recovered from the infected animal and shown to be the same as the organism that was introduced.

However, Redi read a book by William Harvey on generation in which Harvey speculated that insects, worms, and frogs might arise from eggs or seeds too tiny to be seen. The Theory of Biogenesis | Spallanzani's and Pasteur's Experiment With roots in the mid-17th century, multiple scientific scholars and researchers of the day contributed to the tenets of classical cell theory, which postulated that cells represent the basic building blocks of life; all life consists of one or more cells, and the creation of new cells occurs when old .
