Hans Leisegang
German philologist, philosopher and physicist (1890-1951)
Hans Leisegang (March 13, 1890 – April 5, 1951) was a German philosopher and a professor at the University of Leipzig (1920), Jena (1930–34), and Berlin (1948). He was imprisoned for his views on Adolf Hitler during the Nazi era. Leisegang identified philosophy as an interdisciplinary concept of the world and as being synthetic and not analytic. He studied physics and was able to write on the interface of theoretical physics and philosophy.
Life and work
Leisegang was born in Blankenburg as the son of Otto, a military pastor. He studied philosophy, languages, and history at Strasbourg, Paris, and Leipzig. In 1911, he received a doctorate at Strasbourg under Clemens Bäumker and Theobald Ziegler with a dissertation titled “The Concepts of Time and Eternity in later Platonism” (1913), which received a university award. He taught at schools near Markranstädt for some time. He completed his habilitation from the University of Leipzig in 1920 and became a professor in 1925. In 1930, he became a professor of philosophy at the University of Jena.
This brief starts where responsible research should: with the source description of “Hans Leisegang” as german philologist, philosopher and physicist (1890-1951). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as german philologist, philosopher and physicist (1890-1951). Its deeper value depends on whether names, dates, institutions and citations support that framing.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jan 11, 2026. The linked authority identifier is Q105840. VIAF identifies the subject as 44425530. The Library of Congress control number is no98112054. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1890, 1951, 1920 and 1930.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.
