Robert Koch

1843 (Clausthal, Germany) – 1910 (Baden-Baden)

Koch did crucial research on anthrax, tuberculosis, cholera and other diseases, and with his associates was responsible for major advances in laboratory technique. He studied for his doctorate under Henle; they developed an important set of postulates. Cohn helped him by publishing his paper on anthrax; the influential Virchow was however antagonised by his work on tuberculosis. Koch and Pasteur conducted an acrimonious dispute about vaccination, further fuelled by current Franco-German rivalries. Always difficult to work with, Ehrlich, Behring and Kitasato were among his eminent students (he and Behring eventually fell out).
