Why this record matters
A short description can identify a subject without explaining its stakes. For “Fred Van Oystaeyen”, the useful work is to connect “mathematician” to the records capable of establishing context and consequence.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Mar 4, 2026. The linked authority identifier is Q5496460. VIAF identifies the subject as 108675370. The Library of Congress control number is n79007748. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 1972, 1975 and 2007.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
