What is the contribution of Leeuwenhoek?
Antonie van Leeuwenhoek used single-lens microscopes which he made to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas mussels and eels helped disprove the theory of spontaneous generation of life.
