The 19th-century German bacteriologist Robert Koch (1843-1910) came up with rigorous experimental procedures for determining whether a bacterium causes a particular disease.
Robert Koch is generally considered to be one of the two founders of modern bacteriology. The other is Louis Pasteur.
In 1905 Koch won the
Nobel Prize for Physiology or Medicine “For his investigation and discoveries in relation to
tuberculosis”.
