This brief starts where responsible research should: with the source description of “Raz Yirmiya” as researcher. 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 researcher. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q18159261. VIAF identifies the subject as 116686819. The Library of Congress control number is n92801727. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1956, 1990 and 2003.
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.
