Karl Ewald Hasse
German physician (1810–1902)
Karl Ewald Hasse (German: [ˈhasə]; 23 June 1810 – 26 September 1902) was a German physician and professor of special pathology, born in Dresden. He was the son of historian Friedrich Christian August Hasse (1773–1848).
Biography
Hasse studied medicine at the medical-surgical academy in Dresden and at University of Leipzig, earning his doctorate in 1833. Later, he continued his education in Paris and Vienna, and subsequently returned to Leipzig, where in 1836 he received his habilitation. In 1839 he became an associate professor of pathological anatomy in Leipzig, and in 1844 relocated to Zürich, where he was appointed medical director of the cantonal hospital and a professor of pathology.
In 1852 he was appointed professor of special pathology at the medical clinic of the University of Heidelberg, and in 1856 garnered the same position in Göttingen, where he served as medical director until 1878. Among his written works was "Anatomische Beschreibung der Krankheiten der Circulations- und Respirations-Organe", a book that was translated into English by William Edward Swaine and published in 1846 as "An anatomical description of the diseases of the organs of circulation and respiration".
Hasse died in Hanover on 26 September 1902.
He was instrumental in the decision by the Swiss psychiatrist and pioneer of psychosurgery, Gottlieb Burckhardt, to enter the medical field of nervous diseases.

Why this record matters
The phrase “german physician (1810–1902)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q76126. VIAF identifies the subject as 69732482. The Library of Congress control number is n94027193. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1810, 1902, 1773 and 1848.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
