Ehrlich, Paul (1854–1915)




Paul Ehrlich
German bacteriologist and immunologist, the founder of chemotherapy and an early pioneer of hematology. His discoveries include: a method of staining (1882), and hence identifying, the tuberculosis bacillus (see also Robert Koch); the reasons for immunity in terms of the chemistry of antibodies and antigens, for which he was awarded, with Élie Metchnikoff, the 1908 Nobel Prize in Physiology or Medicine; and the use of the drug salvarsan to cure syphilis, the first drug to be used in treating the root causes of the disease (1911).
