[Robert Koch as a young rural doctor in Brandenburg and the Poznan region (1868-1880)].

The bacteriologist and Nobel Prize winner Robert Koch (1843-1910) is one of the most important and best-known scientists in German history. Many people associate him not only with the institute named after him (today the Robert Koch Institute is Germany's National Public Health Institute), but above all, with his work as a "microbe hunter". Koch achieved world fame with the discovery of the tuberculosis pathogen in 1882. To research and combat infectious diseases, he undertook expeditions to foreign countries. This article deals with a lesser-known episode in Robert Koch's life - his years as a young rural doctor in the then Prussian provinces of Brandenburg and Posen. After a chronological description of Robert Koch's "wandering years", the focus is directed to today's culture of remembrance. The question is discussed in which way, if at all, the memory of Robert Koch is maintained at the authentic places.
