This brief starts where responsible research should: with the source description of “Richard Kadison” as american mathematician (1925-2018). 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 american mathematician (1925-2018). 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 Jul 31, 2026. The linked authority identifier is Q2149922. VIAF identifies the subject as 32058986. The Library of Congress control number is n82090181. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1925, 2018, 1996 and 1974.
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.
