Heinrich Hermann Robert Koch (/ k ɒ x / KOKH; [1] [2] German: [ˈʁoːbɛʁt ˈkɔx] ⓘ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist.As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology.
Koch took his research into a new direction—applied research—to develop a tuberculosis treatment and use the profits to found his own research institute, autonomous from government. [17] In 1890 Koch introduced the intended drug, tuberculin, but it soon proved ineffective, and accounts of deaths followed in news press. [18]
Koch's postulates (/ k ɒ x / KOKH) [2] are four criteria designed to establish a causal relationship between a microbe and a disease. The postulates were formulated by Robert Koch and Friedrich Loeffler in 1884, based on earlier concepts described by Jakob Henle , and the statements were refined and published by Koch in 1890. [ 3 ]
The following is a list of notable microbiologists who have made significant contributions to the study of microorganisms. Many of those listed have received a Nobel prize for their contributions to the field of microbiology. The others are typically considered historical figures whose work in microbiology had a notable impact in the field.
Robert Koch. Robert Koch in his laboratory. Pasteur proved that microscopic organisms cause disease and other biological processes like fermentation. Robert Koch, a German physician and contemporary of Louis Pasteur, was also interested in such research. However, Koch was instrumental in the discovery and observation of illness-causing bacteria.
Robert Koch showed that microorganisms caused disease. In 1876, Robert Koch (1843–1910) established that microorganisms can cause disease. He found that the blood of cattle that were infected with anthrax always had large numbers of Bacillus anthracis. Koch found that he could transmit anthrax from one animal to another by taking a small ...

In 1676, Anton van Leeuwenhoek observed bacteria and other microorganisms, using a single-lens microscope of his own design. [3] In 1796, Edward Jenner developed a method using cowpox to successfully immunize a child against smallpox.
The more specific Robert Koch Prize is commonly considered one of the stepping-stones (along with other prizes such as the Lasker Award) to eventual Nobel Prize recognition for scientists in the fields of microbiology and immunology, and a number of Robert Koch Prize winners subsequently became Nobel laureates, such as César Milstein, Susumu ...
