Robert Koch (11 December, 1843–27 May, 1910) a German physician, was the originator of modern bacteriology. He believed that microbes caused diseases in the body. He wished to find the cause for Anthrax. Carrying forward Pasteur's theory of germs, Koch discovered that a certain kind of bacteria stayed in the tissue of the animal that dies of anthrax. When it is injected in any other animal, it can develop anthrax. To prove this theory, he extracted bacteria from an anthrax affected sheep and inserted it in a mouse, which developed anthrax. In 1876, he announced the bacterium that caused Anthrax and named it bacillus anthracis. He developed a method to grow bacteria in solid environment by using broth with gelatine, which made observation easier. He also introduced ways to stain bacteria to improve its visibility, hence, identifying the bacteria that caused cholera and TB. In 1905, he was awarded the Nobel Prize for his tuberculosis findings.
