On March 24, 1882, Robert Koch announced to the Berlin Physiological Society that he had discovered the cause of tuberculosis. Three weeks later, on April 10, he published an article entitled "The Etiology of Tuberculosis" (1). In 1884, in a second paper with the same title, he first expounded "Koch's postulates," which have since become basic to studies of all infectious diseases. He had observed the bacillus in association with all cases of the disease, had grown the organism outside the body of the host, and had reproduced the disease in a susceptible host inoculated with a pure culture of the isolated organism.

Koch continued his studies on tuberculosis, hoping to find a cure. In 1890, he announced the discovery of tuberculin, a substance derived from tubercle bacilli, which he thought was capable of arresting bacterial development in_vitro and in animals. This news gave rise to tremendous hope throughout the world, which was soon replaced
