The Rival Who Built His Own Institute

Robert Koch spent his career proving, one disease at a time, what Louis Pasteur had also spent his career proving from the other side of a national border: that specific microorganisms cause specific diseases. Koch established the causative agents of anthrax, tuberculosis and cholera, and formalized the criteria still used today for linking a microbe to a disease, known as Koch's postulates. The relationship between Koch and Pasteur was never simple collegiality. Historians describe both real personal and national rivalry, sharpened by the politics of the era following the Franco-Prussian War, alongside genuine scientific complementarity: their separate bodies of work together built modern germ theory. In 1891 Koch became the first director of a new Berlin institute built specifically for infectious disease research, the Royal Prussian Institute for Infectious Diseases, later renamed in his own honor as the Robert Koch Institute. It stands today as Germany's federal public health and infectious disease research agency, the institutional legacy of a rivalry that pushed two men, and two nations, toward the same discovery.
