Cohn, Ferdinand Julius (1828–1898)

Ferdinand Cohn

Ferdinand Cohn was a German botanist renowned as one of the founders of bacteriology. He showed that bacteria could be classified in fixed species and discovered that some of these formed endospores (see bacterial spores) which could survive adverse physical conditions. He was also the first to recognize the value of Koch's work on the anthrax bacillus. Cohn began to study bacteria in 1868 and edited Contributions to the Biology of Plants in 1870.
