Robert Koch (Microbiologist)

Robert Koch was a German microbiologist who played a pivotal role in establishing modern bacteriology. He is best known for identifying the specific bacteria responsible for tuberculosis, cholera, and anthrax. Koch developed techniques for isolating and cultivating bacteria, leading to the discovery of the germ theory of disease, which states that many diseases are caused by microorganisms. His work laid the foundation for medical microbiology and earned him the Nobel Prize in Physiology or Medicine in 1905. Koch's postulates, a series of criteria to establish a causative relationship between a microbe and a disease, remain influential in microbiology today.
