Abstract
“In all his work,” Science News-Letter reported on 17 August 1940, “Reyniers follows a slogan of his own, follows it so zealously as to make it almost a fetish: standardization through mechanization.” Utilizing new technologies that he designed and built, James Reyniers came to “wide notice in the world of science” due to his innovative approach to standardizing organisms for use as experimental tools. “Ordinarily, when a scientist wants to study an unknown germ (or drug, or nutrient) he tries it out on an experimental animal,” Life magazine explained in September 1949 when reporting Reyniers’s innovative technologies. “But since all laboratory animals are invariably contaminated by a host of unknown germs, he can never be absolutely sure that results he sees are really caused by the agent he is testing. This problem … can be solved only by using animals whose bodies contain no germs at all. Now, for the first time, such animals are available.” Reyniers had extended the bacteriological ideal of pure culture to encompass the whole organism, creating “bacteriologically blank” organisms, or “biological tabula rasa,” which he believed formed ideal tools for experimental science.
