Ferdinand Julius Cohn(1828-1898) is recognized as one of the founders of modern bacteriology. He contributed to the creation of this discipline in two important ways. First, he invented a new system for classifying bacteria, which provided microbiologists with a more standardized nomenclature with which to work. Secondly, his drive to understand th...
The discipline of bacteriology originated with the recognition that bacteria are organisms in their own right—that they are different from algae, fungi, and other single-celled microorganisms. This idea is central to Cohn's belief in the constancy of bacterial species and his creation of an extensive classification system for microorganisms, in whi...
The notion, promoted by Cohn and others, that bacterial species were constant, led to methods of growing pure cultures. Pasteur was using pure cultures to support his claims that different types of fermentations were caused by specific microorganisms. German physician Robert Koch (1843-1910) would later apply similar reasoning in developing the ger...
