Source-derived summary

Baron Philipp Roger Franz von Neumann (German: Philipp Roger Franz Freiherr von Neumann; English: Philipp Roger Francis Baron de Neumann; 4 December 1781 – 14 January 1851) was an Austrian diplomat.

Early life

Neumann was born in Brussels (then in the Austrian Netherlands), the son of Carl von Neumann (an official in the Habsburg administration) and his wife, Marie Ducpetiaux. Nothing is known of his education, but, since he did not begin work until he was 21, it seems likely that he attended university. His brother was General-major Maximillian Ritter von Neumann (c. 1778–1846).

Career

Neumann began his career in the Austrian Treasury Service in 1802 and was posted to Venice which had come under Austrian control a few years previously. After just over a year he joined the diplomatic service and was posted to Paris where Prince Klemens Wenzel von Metternich was Austrian ambassador.

Later Neumann joined the staff of the Austrian embassy in London under the ambassador Prince Esterházy; Neumann served as chargé d'affaires in his absence. Neumann's activity was regarded as notable, especially in 1814 and 1815, on the occasion of the remittance of the British subsidies to the Austrian government, when he succeeded in obtaining very favourable conditions for Austria on the question of the rate of exchange. He was on excellent terms with the Duke of Wellington, whose grandniece he married, and with Castlereagh.

Editorial summary

The public source identifies “Philipp von Neumann” as austrian diplomat. This brief keeps that definition visible, then builds a research path around Philipp, Neumann and Austrian.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1781, 1851, 1778, 1846—that can be checked directly. The authority record carries competing date values—1778-01, 1781, 1781-12-04—which should remain separate until their references and qualifiers are resolved. Its value is orientation rather than verdict, with Philipp, Neumann and Austrian providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Philipp von Neumann”, the useful work is to connect “austrian diplomat” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 28, 2026. The linked authority identifier is Q3379124. VIAF identifies the subject as 286921008. 4 of 4 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 1781, 1851, 1778 and 1846.

Critical limits

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.
