A German physician and bacteriologist who established the causative agents of anthrax, tuberculosis and cholera, developed criteria still used for linking a specific microbe to a specific disease (Koch's postulates), and served as the first director, from 1891 to 1904, of the Berlin research institute later named in his honor, the Robert Koch Institute. He was awarded the 1905 Nobel Prize in Physiology or Medicine.

Koch and Pasteur: Two Nations, One Theory
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Germ theory is usually told as Louis Pasteur's story, and much of it is. But Robert Koch's contribution was not a footnote to Pasteur's; it was an independent, rigorously different kind of proof. Where Pasteur worked broadly across fermentation, spoilage and vaccination, Koch built a method: isolate the microbe, grow it in pure culture, reintroduce it into a healthy host, and confirm the same disease results. Applied first to anthrax and then to tuberculosis and cholera, that method, Koch's postulates, gave germ theory something it had lacked, a repeatable test that other scientists anywhere could run for themselves. The Medicine Atlas records Koch as an independent, variant discoverer alongside Pasteur on the Germ Theory of Disease entry, not because the two men agreed, personally or nationally, but because the historical record supports crediting both. Koch's own path led him to found and direct, from 1891 to 1904, the Berlin institute that today bears his name, a research legacy built directly on the rivalry.

Louis Pasteur, Healers Historians document both real personal and national rivalry between Koch and Pasteur, sharpened by Franco-Prussian War-era politics, and genuine scientific complementarity: their work together formed the basis of modern germ theory.

Discoveries
Why this is disputed. Italian physician Filippo Pacini had correctly identified the comma shaped bacillus in 1854, but his work went largely unnoticed; the independent 1884 isolation by Robert Koch in pure culture is the finding that brought the organism to wide scientific attention.
Held Differently
Koch independently and rigorously established that specific microorganisms cause specific diseases through his anthrax, tuberculosis and cholera work, formalized as Koch's postulates, alongside Louis Pasteur's own germ theory research.

What are Koch's postulates?
Koch's postulates are Robert Koch's criteria for linking a specific microbe to a specific disease, developed while he established the causes of anthrax, tuberculosis and cholera.
Koch's postulates are criteria, developed by the German physician and bacteriologist Robert Koch, for linking a specific microbe to a specific disease. Koch used them while establishing anthrax, tuberculosis and cholera as caused by particular bacteria, and they are still used today. He served as the first director of the Berlin research institute later named in his honor, the Robert Koch Institute, from 1891 to 1904, and was awarded the 1905 Nobel Prize in Physiology or Medicine.
