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. Opinions about why diseases afflicted people differed between cultures and parts of society and the treatments differed as well. He read in the book on generation by William Harvey a speculation that vermin such as insects, worms, and frogs do not arise spontaneously, as was then commonly believed, but from seeds or eggs too small to be seen.

Spallanzani had many findings against epigenesist and the role of sperm which he identified as "animalcules" in generation (1). Virchow used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular level.

At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. More important there was an acceptance of their work by the scientific community throughout the world and a willingness to continue and expand the work. At that time, it was widely held that maggots arose spontaneously in rotting meat. According to Hunt, Redi had a least one son, who achieved some renown in literature.
