Ferdinand Cohn

Died 25 Jun 1898 at age 70 (born 24 Jan 1828).Ferdinand (Julius) Cohn was a German naturalist and botanist who is considered one of the founders of bacteriology and known for his studies of algae, bacteria, and fungi, insect epidemics and plant diseases. From his early studies of microscopic life he developed theories of the bacterial causes of infectious disease and recognized bacteria as plants. He showed that the protoplasm was almost identical in plant and animal cells. He founded the science of bacteriology with a three volume treatise published in 1872 which classified bacteria into genera and species. Cohn gave Robert Koch a position in his lab and aided him in preparing Koch's famous work on anthrax.
