Anton van Leeuwenhoek was the first person to observe microscopic single-celled organisms using a microscope that he designed himself. Although Robert Hooke also used a microscope to observe cells, he did not observe living cells, but rather dead cork cells. Matthias Schleiden was a botanist who proposed the cell theory, stating that all living organisms are composed of cells. Louis Pasteur was a microbiologist who made significant contributions to the field of microbiology, including the discovery of the germ theory of disease.
