Lazzaro Spallanzani (1729-1799) | The Embryo Project Encyclopedia In the 1830s, Theodor Schwann showed that microorganisms do not spontaneously generate. In 1837, Italian zoologist Filippo de Filippi named the larval stage of the parasitic fluke "redia" in honor of Redi. 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. The Theory of Spontaneous Generation. The fish and veal rotted in both groups, but maggots only formed in the jars open to air. For much of history, people believed that animals could come.
