Ehrlich, Paul

Ehrlich, Paul

Ehrlich, Paul, 1854-1915, German bacteriologist. He directed (1896) an institute for serum research at Steglitz, near Berlin, that was transferred (1899) to Frankfurt-am-Main as the Institute for Experimental Therapy. For his work in immunology he shared with Élie Metchnikoff the 1908 Nobel Prize in Physiology or Medicine. He made valuable contributions also in hematology, in cellular pathology, in the use of dyes in microscopy and in the treatment of disease, in the study of cancer, and in his discovery of salvarsan (or "606," so called from its numerical order in his experimental series) and of neosalvarsan (less toxic than salvarsan) for the treatment of syphilis.

(born March 14, 1854, Strehlen, Silesia, Prussia—died Aug. 20, 1915, Bad Homburg vor der Höhe, Ger.) German medical scientist. After early work on distribution of foreign substances in the body and on cell nutrition, he found uses for staining agents in diagnosis (including that of tuberculosis) and treatment. He also researched typhoid, fever medications, and eye diseases. In one paper, he showed that different tissues' oxygen consumption reflected the intensity of their cell processes. Ehrlich developed a method of stimulating production of antitoxins by injecting increasing amounts of toxin into animals; his work was crucial to the creation of a diphtheria antitoxin. He and Élie Metchnikoff received the 1908 Nobel Prize for Physiology or Medicine. With Sahachiro Hata, he developed Salvarsan, the first effective syphilis treatment, in 1910.
