Medical Eponyms
Bundle of His (1893)
The atrioventricular bundle (bundle of His) arises in the specialised tissue of the atrioventricular node (AV node, Tawara node), and continues in the interventricular septum as a single bundle, the crus commune. It divides into two trunks that pass respectively to the right and left ventricles, fine branches passing to all parts of the ventricles. The bundle of His conducts impulses from the atria to the Purkinje fibres of the ventricles, and initiates ventricular contractions.
In 1893, His reported the atrioventricular bundle. He described the bundle on one page of his 36 page dissertation:

Nach längerem Nachforschen ist es mir jedoch gelungen, ein Muskelbündel zu finden, welches Vorhof- und Kammerscheidewand untereinander verbindet, und welches bisher der Beobachtung dadurch sich entzogen hat, dass es, bei geringem Umfange, nur dann in ganzer Ausdehnung sichtbar wird, wenn die Scheidewände genau der Länge nach getrotfen sind. Sowohl auf derartigen Schnitten, als auch in Schnittserien konnte ich den Verlauf des Bündels erkennen, und habe dasselbe bisher nachgewiesen bei einer ausgewachsenen Maus, einem neugeborenen Hunde, zwei neugeborenen und einem erwachsenen (ca. 30jährigen) Menschen (Fig. 4). Das Bündel entspringt von der Hinterwand des rechten Vorhofs, nahe der Vorhofsscheidewand, in der Atrioventricularfurche, legt sich der oberen Kante des Kammerscheidewandmuskels unter mehrfachem Faseraustausch an, zieht auf demselben nach vorn, bis es, nahe der Aorta, sich in einen rechten und einen linken Schenkel gabelt, welch letzterer in der Basis des Aortenzipfels der Mitralis endigt.
After extensive investigation I was able to find a muscle bundle which connects the atrial and ventricular septal walls, and which apparently has not been observed before, because it is only visible in its entire distribution when the septal walls are cut exactly in the horizontal direction. I was able to recognise the course of this bundle on such sections, and have proved its presence in an adult mouse, a new born-dog, two new-born infants and one adult around 30 years of age (Fig. 4). The bundle arises from the posterior wall of the ventricle near the atrial septum in the atrioventricular groove, it joins the upper edge of the ventricular septum and ramifies, coursing on the septum anteriorly until it branches near the aorta into a right and left branch, the latter terminating in the base of the aortic cusp of the mitral valve.

Ob dieses Bündel wirklich die Erregung vom Vorhof zum Ventrikel leitet, kann ich nicht mit Sicherheit angeben, da ich bisher Durchtrennungsversuche an demselben nicht angestellt habe. Jedenfalls ist dessen Vorhandensein ein Grund gegen die Meinung derjenigen, welche mit dem Mangel musculösen Zusammenhanges zwischen Vorhof und Kammer die Nothwendigkeit nervöser Leitung zu beweisen suchen.
I cannot state with certainty whether this bundle actually conducts the impulses from the atrium to the ventricle, as I did not perform any experiments dealing with the severing of the bundle. Its presence, in all events, is contrary to the opinion of those, who, in the absence of such a muscular connection between the atrium and the ventricle, attempt to prove the necessary presence of a nerve conduction
Werner-His disease (1916)
Trench fever [** aka five-day fever; quintan fever; Wolhynia fever; His disease; Meuse fever; shin bone fever] is a self-limiting Rickettsial infection which caused outbreaks affecting over 1 million soldiers in Europe during World War I. The infecting organism is Bartonella quintana (formerly Rochalimaea quintana; Rickettsia quintana), an aerobic, Gram-negative rod-shaped bacillus. The primary vector is the human body louse.

Controversies
While His Jr was not known to be an active antisemite or Nazi sympathizer, the same cannot be said with respect to his views of the mentally ill. In his official rector’s address in 1928, entitled Über die natürliche ungleichheit des menschen, His emphasized the evils of contemporary culture which he believed could be eliminated by eugenic measures.
