Ferdinand Cohn (born January 24, 1828, Breslau, Silesia, Prussia [now Wrocław, Poland]—died June 25, 1898, Breslau) was a German naturalist and botanist known for his studies of algae, bacteria, and fungi. He is considered one of the founders of bacteriology. Cohn was born in the ghetto of Breslau, the first of three sons of a Jewish merchant.

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...

Sep 13, 2023 · Ferdinand Julius Cohn (January 24, 1828 – June 25, 1898) was a German biologist. His classification of bacteria into four groups based on shape (sphericals, short rods, threads, and spirals) is still in use today. Among other things Cohn is remembered for being the first to show that Bacillus can change from a vegetative state to an endospore ...
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.
Jul 1, 2000 · The discovery of sexuality and development in microorganisms and Darwin’s theory of evolution contributed to the founding of microbiology as a science. Ferdinand Cohn (1828–1898), a pioneer in the developmental biology of lower plants, considerably promoted the taxonomy and physiology of bacteria, discovered the heat-resistant endospores of ...

May 23, 2018 · Ferdinand Cohn. Considered to be the father of modern bacteriology, Ferdinand Cohn (1828-1898) began his studies as a botanist and ultimately made discoveries which led to the creation of a new field of study. He was the first scientist who believed that bacteria should be classified as plants. His contributions include a system of ...
Cohn’s work also helped establish the recognition of bacteria as a separate group of living organisms different from plants or animals. Ferdinand was born on January 24, 1828 in Breslau (now Wroclaw), Lower Silesia, now in Poland. His father, Issak Cohn, was poor and lived in Breslau’s Jewish ghetto when Ferdinand was born.
