Koch is also responsible for identifying the causative agents behind cholera and anthrax, but his most important contribution comes in the form of figuring out how to study bacteria. His research led to creation of four generalized principles also known as Koch’s postulates that link specific microorganisms to specific diseases. It still remains the gold standard for studying microorganisms in medical biology. Also Read - Google adds 3D monuments to AR Search results: How to use

He first isolated the bacterial cultures on potato slices, and was one of the first to adopt the use of Petri dish, also denoted in today’s Google Doodle. He is also credited with the use of agar to grow and isolate pure cultures. His research is mainly responsible for studying how the bacteria grows, how to fight them and most importantly, the useful chemicals produced by them.

In 1890, Koch announced that he had discovered the cure for Tuberculosis. However, his attempt to develop a drug treating tuberculosis called tuberculin failed, and was released in the market without enough testing. Koch tested Tuberculin, consisting of proteins he had extracted from the tuberculosis bacterium on guinea pigs and a handful of people. He observed that humans contracted worse side effects than guinea pigs, but he was optimistic to get the drug released to the market.

Koch was awarded the Nobel Prize in 1905 for discovery of Mycobacterium tuberculosis, the pathogen causing the disease. In 1908, Robert Koch medal was established to honor the work of the greatest living physicians. He died in 1910, three days after delivering a lecture on his tuberculosis research at the Prussian Academy of Sciences.
