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 Aug 30, 2026. The linked authority identifier is Q708247. VIAF identifies the subject as 89512766. The Library of Congress control number is n79060714. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
