With his superior light adjusting techniques, Leeuwenhoek was able to construct microscopes which could magnify over 200 times, enabling him to perceive small "animalcules" or bacteria in water.

Furthermore, in a letter, he reports how he had discovered in the plaque of two old men who had never brushed their teeth in their lives “an unbelievably great company of living animalcules, a-swimming more nimbly than any I had ever seen up to this time.
