At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. He was the founder of the Pasteur Institute, Paris. 6 What were the contributions of Hooke and van Leeuwenhoek to the field of microbiology How did they make these contributions?
