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...

May 23, 2018 · Cohn, Ferdinand Julius (1828-1898) German microbiologist. Ferdinand Cohn, a founder of modern microbiology, became the first to recognize and study bacteriology as a separate science. Cohn developed a system for classifying bacteria and discovered the importance of heat-resistant endospores.
Cohn was a prolific writer, leaving behind over 150 papers, essays, and books. [1] In the 1850s he studied the growth and division of plant cells. In 1855 he produced papers on the sexuality of Sphaeroplea annulina and later Volvox globator. In the 1860s he studied plant physiology in several different aspects.
In 1856, he demonstrated the same phenomenon in Volvox globator, a motile alga. The same year, he was appointed chairman of the botanical sections. Between 1856 and1866, Cohn did some work on the contractile tissues of plants, and also pioneered the phototrophic studies of microscopic organisms.
