'''Hermann Ludwig Eichhorst''' (3 March 1849 – 26 July 1921) was a German-Swiss [[internist]]

==Biography==
Eichhorst was born in [[Königsberg]]. He studied medicine in Königsberg and [[Berlin]], and was an assistant to [[Ernst Viktor von Leyden]] (1832–1910), [[Bernhard Naunyn]] (1839–1935), and [[Friedrich Theodor von Frerichs]] (1819–1885). In 1884 became director of the medical clinic in [[Zürich]], where he remained for the rest of his career.

Eichhorst made contributions in several fields of medicine. In an 1878 [[monograph]] he documented one of the earliest descriptions of progressive [[pernicious anemia]]. He also discovered globular forms in the [[poikilocytosis]] of this disease, which were to become known as "Eichhorst's corpuscles". In 1896 and 1913 respectively, Eichhorst provided early accounts of infantile and hereditary [[multiple sclerosis]]. He also described a form of interstitial [[neuritis]] that is sometimes referred to as "Eichhorst's neuritis".
