Why this record matters

The linked authority identifier is Q15080210. VIAF identifies the subject as 41664642.

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.
