Robert Koch
Best known for demonstrating that specific microorganisms cause specific diseases, German bacteriologist and physician helped to confirm the germ theory of disease.
Robert Koch’s research on tuberculosis was interrupted by a cholera outbreak in Egypt due to the significant risk of the disease spreading to Europe.1
As a member of a German government commission, Koch was dispatched to Egypt to investigate the epidemic. While he suspected a specific comma-shaped bacterium was the cause, the outbreak subsided before he could confirm his hypothesis. Consequently, he traveled to India, where the disease was endemic, to complete his investigation. There, he successfully identified the organism responsible for cholera and determined that it was transmitted through contaminated drinking water, food, and clothing. Following this mission, Koch resumed his work on tuberculosis.1
