Who discovered the disease?

Robert Koch: Robert Koch was a German physician and microbiologist who is considered to be one of the founders of modern bacteriology. He made significant contributions to the field of microbiology, including the development of Koch's postulates, which are a set of criteria used to establish a causal relationship between a microorganism and a specific disease. Koch also discovered several important pathogens, including the bacteria that cause tuberculosis, anthrax, and cholera.
