Johann Friedrich Ruthe
German botanist (1788-1859)

Johann Friedrich Ruthe Ruthé or von Ruthe (16 April 1788 in Eggenstädt, near Hildesheim – 24 August 1859 in Berlin) was a German teacher (Oberlehrer), botanist and entomologist. In the field of entomology he specialised in Hymenoptera and Diptera.
With assistance from Heinrich Friedrich Link (1767–1851) he began his studies at the University of Berlin in 1811. Here he had as instructors Karl Rudolphi (1771–1832) and Martin Lichtenstein (1780–1857). After concluding his university studies, he taught classes at several schools in Berlin and Frankfurt an der Oder. Due to poor health he retired from teaching in 1842. Ruthe issued the exsiccata work Flora der Mittelmark in getrockneten Exemplaren (1820–1822).
The fungi genus Ruthea is named after him, now a synonym of Paxillus. Also in 1976, botanists A.Hansen & G.Kunkel published Rutheopsis, a genus of flowering plants from the Canary Islands belonging to the family Apiaceae, also named in his honour.
Written works
Among his written works was a textbook on zoology, "Handbuch der Zoologie", that was co-authored with Arend Friedrich August Wiegmann (1802–1841).
This brief starts where responsible research should: with the source description of “Johann Friedrich Ruthe” as german botanist (1788-1859). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as german botanist (1788-1859). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 4, 2026. The linked authority identifier is Q6215830. VIAF identifies the subject as 43968648. The Library of Congress control number is no2002059192. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1788, 1859, 1767 and 1851.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
