Photographic reproduction portrait of German physician and microbiologist, Robert Koch (1843-1910). Koch is considered one of the founders of modern bacteriology due to his identification of the causative agents of tuberculosis, cholera, and anthrax. He was the first to demonstrate the transmission of infectious diseases artificially from animal to animal and devised most of the best methods for sterilization and disinfection. Koch received the Nobel Prize in Physiology or Medicine in 1905. His portrait precedes a chapter describing Koch's life and contributions fully.

This plate is found in the publication, The History of Inoculation and Vaccination for the Prevention and Treatment of Disease, a book on the history of vaccination associated with the American Medical Association's 1913 Annual Meeting, which took place in Minneapolis, Minnesota.

This is followed by a supply catalog section, a pharmaceutical products section, advertisements for medical products, awards given by the Wellcome Chemical Research Laboratories, and drawings of the Wellcome research laboratories located in London, England as well as their office in New York City, New York.
