The identification of a specific bacillus in 1880 provided the breakthrough necessary to understand the etiology of typhoid fever. Karl Joseph Eberth, a German pathologist and bacteriologist, observed the organism responsible for the disease, an achievement later confirmed by Georg Theodor August Gaffky in 1884, leading to the classification of the pathogen known historically as the Gaffky-Eberth bacillus.
Academic Training and Career
Born in 1835 in Würzburg, Eberth received his education at the University of Würzburg, where he obtained his doctorate in 1859. His early professional career included a period as an assistant to the anatomist Albert von Kölliker. He later transitioned into academia, serving as a full professor of pathological anatomy at the University of Zurich starting in 1869. In 1881, he moved to the Martin Luther University Halle-Wittenberg, where he remained as a professor until his retirement in 1911.

Beyond his work on typhoid, Eberth made several anatomical discoveries that bear his name. Eberth's lines refer to microscopic structures observed between myocardial cells when stained with silver nitrate. He also identified Eberth's perithelium, defined as an incomplete layer of connective tissue cells surrounding blood capillaries. His research output was extensive, covering diverse topics in biological sciences and medicine.
Published Scientific Works
Eberth authored various texts throughout his career. His 1863 work, Untersuchungen über nematoden, explored nematode research, while his 1872 publication, Zur Kenntnis der Bacteritischen Mykosen, focused on bacterial infections. Later contributions include his 1887 study on blood platelets in lower vertebrates and his 1888 collaboration with Curt Schimmelbusch, Die Thrombose nach Versuchen und Leichenbefunden. In 1904, he published Die männlichen Geschlechtsorgane.
