Robert Koch

German physician and pioneering microbiologist, 1843-1910

"The founder of modern bacteriology, Koch is known for his role in identifying the specific causative agents of tuberculosis, cholera, and anthrax and for giving experimental support for the concept of infectious disease. In addition to his trail-blazing studies on these diseases, Koch created and improved laboratory technologies and techniques in the field of microbiology, and made key discoveries in public health. His research led to the creation of Koch’s postulates, a series of four generalized principles linking specific microorganisms to specific diseases that remain today the ""gold standard"" in medical microbiology. As a result of his groundbreaking research on tuberculosis, Koch received the Nobel Prize in Physiology or Medicine in 1905."

Letter rich in content about his studies for mosquitos to a young fellow, apparently Giovanni Galli, who regularly compiled mosquito deliveries for Koch’s malaria research: „The last parcels of mosquitos, also the ones from Colico I received in good order. The continued monitoring of mosquitos that appear in Vernato led into an interesting result. We found out that the same cirumstances are existing like in other fever areas that are long way away, like Szilia and in the northern part of Germany in the swamp areas of the Weser.

Unfortunately I won’t be able to continue my important studies as I have to leave in the next days Grosseto to travel via Rome and Naples to Batavia. Maybe we can continuing the mosquito collection upon my return again. – Somewhat browned and with tear to folds (old re-backed)..

To an unnamed colleague, probably the food chemist Gustav Rupp at Karlsruhe University, apologizing for not knowing anyone suitable for a vacant position: "Unter den mir bekannten jüngeren Bakteriologen und Hygienikern habe ich Umschau gehalten, aber weder selbst eine geeignete Persönlichkeit für die Assistentenstelle an der Station für Lebensmittel-Untersuchungen finden können, noch auch von Anderen, die ich, natürlich in diskreter Weise, um Auskunft gebeten habe, etwas erfahren können, was Ihren Zwecken gedient hätte. Ich bedaure daher sehr, Ihnen in dieser Angelegenheit keine Vorschläge machen zu können […]". - The great German physician and pioneering microbiologist is regarded as the founder of modern bacteriology; he is known for his role in identifying the specific causative agents of tuberculosis, cholera, and anthrax and for giving experimental support for the concept of infectious disease.
