The identification of the specific bacillus responsible for typhoid fever in 1884 remains the defining achievement of Georg Theodor August Gaffky. Operating at the dawn of modern bacteriology, his precise laboratory methods provided the empirical confirmation required to link this infectious agent to the disease, forever altering the diagnostic framework for human health.
Early Medical Training
Born in Hanover in 1850 to shipping agent Georg Friedrich Wilhelm Gaffky and Emma Schumacher, he pursued his education at the Friedrich Wilhelm University in Berlin. His academic trajectory faced a significant pause during the Franco-Prussian War of 1870. Returning to his studies, he completed his doctorate in 1873, presenting a dissertation that explored links between kidney disease and lead poisoning. After obtaining his qualification, he served as a physician within the military and gained clinical experience as an assistant at the Berlin Charité hospital.

Gaffky joined the circle of Robert Koch, where he contributed to the development of rigorous bacteriological protocols. This period focused on systematic techniques for isolating microorganisms. By refining cultivation methods in gelatin and other substrates, he effectively advanced the study of infectious pathologies. His work was pivotal in isolating the organism later known as the Gaffky-Eberth bacillus, confirming its presence in 26 out of 28 observed typhoid cases.
Global Infectious Disease Investigations
His expertise in infectious pathogens led to his participation in international research missions. He traveled to Egypt to assist in examining the transmission vectors of cholera. During the 1892 outbreak of the same disease in Hamburg, he acted as a government advisor. Furthermore, he directed a large-scale investigation into the 1897 bubonic plague epidemic in India. His career culminated in his tenure as the director of the Berlin Institute for Infectious Diseases, a position he occupied from 1904 until 1913.
