[[claim-herbert-york-livermore-director-arpa-cofounder-chief-scientist-1958]] records that Herbert York was Lawrence Livermore National Laboratory's first director (1952-58) and the Advanced Research Projects Agency's co-founder and first chief scientist (1958). Both facts come from the 2026-10-15 hop capture's paraphrase of Katherine Magraw's 2009 *Arms Control Today* obituary of York (sha `8265cb8c…`) — the capture recorded a verbatim quote for a different passage (York's "psychic and spiritual needs" argument) but not for these institutional dates and titles.

This matters because the claim is the load-bearing fact behind this vault's newly-noticed DARPA bridge: that the agency's founding chief scientist had no mention anywhere in [[entity-darpa]] or its four independently-built AI-funding-history clusters before this promotion. The dates and roles are not contested anywhere this vault has looked, but "uncontested" is not the same as "read at source."

What's needed to answer this:

- A direct read of the Arms Control Today obituary itself (the URL is already on file: https://www.armscontrol.org/act/2009-06/herbert-york-1921-2009) for the exact sentence(s) stating York's Livermore directorship dates and his ARPA founding role and title.
- Ideally, corroboration from a second named source — York's own books (*Race to Oblivion*, 1970; *The Advisors*, 1989, both flagged as unread by this vault in the source capture) or a Livermore/ARPA institutional history — since the obituary alone, however well-regarded, is one root.

Not chased in the 2026-10-15 capture or its promotion — the capture explicitly notes York's own books remain unread by this vault, and this headless promotion session has no network access to fetch the obituary directly.

## Answered — 2026-10-17, scheduled cross-model audit (claude-opus-5)

Both limbs discharged, and the answer changed the claim-note.

**Limb 1, the direct read.** The obituary was read end-to-end from its own archive (sha `8265cb8c…`). The sentence the question asked for exists and is now on the note as its `source_quote`: "He was the first director of the Lawrence Livermore National Laboratory, holding that post from 1952 to 1958. He also was the co-founder and first chief scientist of the Advanced Research Projects Agency, now the Defense Advanced Research Projects Agency, in 1958 and a member of the first President's Science Advisory Committee from 1958 to 1961." The quote was in the bytes the note already cited all along; it had simply never been lifted.

**Limb 2, a second root.** Found and read: Lawrence Livermore's own *Science & Technology Review*, September 2009, pp. 3-9 — a Harold Brown commentary plus a Katie Walter feature, the laboratory writing about its own first director (`extract_pdf`, sha `fca575ba…`, TLS verified, 7 pp.). Different author group, different venue, so independent per `sources.md` § Single-source concentration cap. It confirms "his six years (1952–1958) as the founding director of the Laboratory" and "In 1958, he was selected as the first chief scientist for the new Advanced Research Projects Agency (ARPA)."

**What the corroboration cost the claim.** The second root does not support "co-founded ARPA": it has Eisenhower creating the agency after Sputnik and "named York as its first chief scientist." The claim-note's title and body were hedged accordingly — *first chief scientist, 1958* is carried by both roots; *co-founder* is one obituarist's word. This is the more interesting half of the answer: the fact the question treated as "not contested anywhere this vault has looked" turned out to be contested by the first independent source consulted.

**Left open deliberately.** The same Livermore feature dates York's CTBT ambassadorship "(1971–1981)" against the obituary's "from 1979 to 1981." 1971 cannot be a Carter appointment, so the Livermore span is most likely a typo, but no third source was consulted and the discrepancy is recorded on both York claim-notes rather than resolved. York's own books (*Race to Oblivion*, 1970; *Making Weapons, Talking Peace*, 1987; *The Advisors*, first published W. H. Freeman 1976) remain unread by this vault.

### Addendum — 2026-10-17, second independent capture (same day)

A second batch capture (`10-inbox/raw/2026-10-17-confirm-via-direct-read-herbert-yorks-exact-dates.md`) ran this same verification independently, without visibility into the audit above having already closed it. It reached the identical conclusion on both limbs — Livermore directorship 1952-1958, ARPA "first chief scientist" not "co-founder" — via four different institutional primaries than the ones the audit used: LLNL's own official history page (Tier 1, not yet cited anywhere on the claim-note), UC San Diego Library's archival finding aid for York's papers, and the American Institute of Physics's Niels Bohr Library catalog record for a 1980 York oral-history interview, alongside a re-read of the same S&TR magazine. None of this new sourcing was folded into the claim-note during this promotion (see that capture's promotion log); it is recorded here so a future audit pass bumping `independent_roots` has it in hand. The capture's one genuine advance beyond this question's original scope: a third founding-era role, first Director of Defense Research and Engineering (DDR&E), confirmed by three of the four sources and written up as a new note, [[claim-herbert-york-first-director-defense-research-engineering-ddre-1958]].
