This article explores one of a citation classics in medical literature-Koch's postulates. It analyses their creation in the nineteenth century and their popularity in the twentieth century. As a genre of historiography, references to the postulates are anecdotes. In referring to a historical event that never happened, such references serve to remind their audiences of a tradition of experimental medicine that supposedly originated with Robert Koch.
Keywords: Disease causation; Koch's postulates; Medical microbiology.
