Ehrlich. (n.d.). In YourDictionary. Retrieved from https://www.yourdictionary.com/Ehrlich
German bacteriologist who was a pioneer in the study of the blood and the immune system, and in the development of drugs to fight specific disease-causing agents. He discovered a compound that was effective in combating sleeping sickness as well as a drug, called salvarsan, that cured syphilis.
Abraham Ehrlich started the company in 1954 when he started his career offering auto insurance products to auto dealers throughout Southern California.
The agency grew as Robert Ehrlich also joined the company and before long they found that the insurance products they offered were not sufficient.
This result, which is usually known now as the " Ehrlich phenomenon," was explained by him on the supposition that the " toxin " does not represent molecules which are all the same, but contains molecules of different degrees of combining affinity and of toxic action.
The most important works on immunity are: Ehrlich, Studies in Immunity (English translation, New York, 5906), and Metchnikoff, Immunity in Infective Diseases (English translation, Cambridge, 1905).
The latter view, first advocated by Ehrlich, harmonizes with the facts established with regard to toxic action and the behaviour of antitoxins, and may now be regarded as established.
