Johann Radon
Austrian mathematician (1887-1956)
Johann Karl August Radon ([ˈʁaːdɔn]; 16 December 1887 – 25 May 1956) was an Austrian mathematician. His doctoral dissertation was on the calculus of variations (in 1910, at the University of Vienna).
Life
Radon was born in Tetschen, Bohemia, Austria-Hungary, now Děčín, Czech Republic. He received his doctoral degree at the University of Vienna in 1910. He spent the winter semester 1910/11 at the University of Göttingen, then he was an assistant at the German Technical University in Brno, and from 1912 to 1919 at the Technical University of Vienna. In 1913/14, he passed his habilitation at the University of Vienna. Due to his near-sightedness, he was exempt from the draft during wartime.
In 1919, he was called to become Professor extraordinarius at the newly founded University of Hamburg; in 1922, he became Professor ordinarius at the University of Greifswald, and in 1925 at the University of Erlangen. Then he was Ordinarius at the University of Breslau from 1928 to 1945.
After a short stay at the University of Innsbruck he became Ordinarius at the Institute of Mathematics of the University of Vienna on 1 October 1946.
Begin with the source’s own compact description: “Johann Radon” is austrian mathematician (1887-1956). The dossier treats that line as a proposition to test through Johann, Radon and Austrian, not as a finished interpretation.
Why this record matters
The phrase “austrian mathematician (1887-1956)” 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.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q78580. VIAF identifies the subject as 69008598. The Library of Congress control number is n89657771. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1887, 1956, 1910 and 1912.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
