A major contribution of microbiology has been learning the role of microbes in disease.
Louis Pasteur (1822-1895) and Robert Koch (1843-1910) were contemporaries of Cohn’s and are often considered to be the founders of medical microbiology.
Anton van Leeuwenhoek (1632 - 1723), was a Dutch tradesman who is well known for his contribution towards the establishment of microbiology and for improvements to the microscope.
Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation, thereby solidifying microbiology’s identity as a biological science.
Microbiology is the study of microorganisms (microbes), which are organisms (forms of life) that are microscopic; that is, too small to be visible to the naked or unaided human eye.
Beijerinck made two major contributions to microbiology: the discovery of viruses and the development of enrichment culture techniques.
Microbiology has detailed how abundant microbes are and how they are critical to food chains and decomposing dead plants and animals, releasing their nutrients for reuse.
