1906

Opening of George Speyer Haus, adjacent to the Royal Institute for Experimental Therapy in Frankfurt, where Ehrlich pursued (and named) chemotherapy of infectious diseases (i.e., experimental chemical therapy), especially directed at parasitic/protozoan diseases resistant to serum therapy (Bäumler, 114ff.). Ehrlich, in speech inaugurating his Institute for Experimental Therapy in Frankfurt, introduces term “chemotherapy” “to stand for the destruction of disease-causing microorganisms in the human or animal host by means of chemical compounds introduced into the host organism” (Lesch III, 15ff). British public was introduced to “chemotherapy” in Ehrlich’s sense only in 1938-1939, following discovery of M&B 693 (Sulfapyridine) by May & Baker (Lesch III, 185-188).
