Robert Koch

His work led not only to scientific discoveries, but also to a public transformation in conceptions of personal hygiene as a way to prevent sickness and disease.

Koch was directly responsible for shaping public health in the early twentieth century, based on knowledge of microbes as the origin of disease.

Most of Robert Koch’s life and work belong firmly to the nineteenth century,

but he also had considerable influence on the twentieth century.

Many of the fundamental principles of bacteriology were developed or modified by him and his colleagues in Berlin.

He became an international celebrity for his isolation of the agents of anthrax, tuberculosis, and cholera, all scourges of the nineteenth century.

He developed a method of identification by isolating a microorganism in tissue, then injecting it into a healthy individual; if the identical disease resulted, the proper agent had been identified.

He also had shown that the tubercle bacillus was present in sputum; the implication was that there was a widespread ignorance about the contagious effects of spitting, coughing, and even breathing.

When typhoid fever broke out in the Ruhr region of Germany in 1901, Koch was recruited to help find ways of containing it. Koch emphasized the need for sanitary water supplies and sewage disposal as well as the need to avoid contact with those already infected. He began investigations of the spread of the disease, which resulted in the creation of new laboratories and health officials trained in bacteriology. His efforts helped to halt the epidemic and reduce the death toll.

His work in bacteriology provided not only a basis for scientific study of microorganisms, but also a transformation of public understanding of disease; his work demonstrated the need for rigorous public health measures.

Koch posited the novel hypothesis that some diseases, such as diphtheria and typhoid, could be carried by healthy individuals—showing no symptoms—and passed on to others.

Thus at the dawn of the twentieth century, public health officials were confronted with the severe challenges of tracking, and halting, infections across populations.
