Leeuwenhoek made microscopes consisting of a single high-quality lens of very short focal length. 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. At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter.
