jan 1, 1882 - Robert Koch



Robert Koch was a German doctor and scientist who was, after reading Pasteur's work, inspired to start studying microbes. He managed to prove what Pasteur couldn't: microbes caused disease. He went on to identify the specific microbes that caused TB in 1882 and Cholera in 1883 aswell as the anthrax bacterium.

Koch also developed a new way of growing bacteria in agar jelly and discovered that bacteria are easier to see if they are stained. These new methods were used and copied by other scientists to discover new microbes.

This was a huge breakthrough that sparked competition between Pasteur and Koch who constantly tried one-up each other and opened the gateway to may more discoveries of specific microbes (some by Pasteur himself).

Koch's work had a much greater influence on medical Britain and inspired others to research into microbes. However it still took time for most doctors and the government to accept the Germ Theory of Disease. Even thought the real cause of disease had been discovered it still took a while before it affected medical treatment and prevention.

Like Pasteur's discovery, Koch's work had a direct impact on the prevention and treatment of many diseases once accepted.
