Francesco Redi: Biography, Achievements & Lasting Legacy

Having a doctoral degree in both medicine and philosophy from the University of Pisa at the age of 21, he worked in various cities of Italy. A rationalist of his time, he was a critic of verifiable myths, such as spontaneous generation. His most famous experiments are described in his magnum opus Esperienze intorno alla generazione degl'insetti (Experiments on the Generation of Insects), published in 1668. He disproved that vipers drink wine, can break glasses and that their venom is poisonous when ingested. He correctly observed that snake venoms were produced from the fangs, not the gallbladder, as was believed. He was also the first to recognize and correctly describe details of about 180 parasites, including Fasciola hepatica and Ascaris lumbricoides. He also distinguished earthworms from helminths (like tapeworms, flukes, and roundworms). He possibly originated the use of the control, the basis of experimental design in modern biology. A collection of his poems first published in 1685 Bacco in Toscana (Bacchus in Tuscany) is considered among the finest works of 17th-century Italian poetry, and for which the Grand Duke Cosimo III gave him a medal of honour.
