Herbert York's own 1975 interview, and ARPA's own commissioned history, name him "Chief Scientist," not Director — resolving the vault's York-director contradiction
Herbert York described his own 1958 move into the newly created Advanced Research Projects Agency (ARPA) in a direct interview conducted by Richard J. Barber Associates, Inc. for ARPA's own 1975 commissioned institutional history: "it's no accident... that I went from membership on the President's Scientific Advisory Committee to be Chief Scientist of ARPA," crediting James R. Killian Jr., PSAC's chairman, with the selection. The report's own description of ARPA's earliest organization makes the title distinction explicit: "The Director's Office consisted simply of Johnson and the Chief Scientist (York)" — York as a named subordinate position inside the Director's Office, not a co-equal or predecessor director.
The report's preface draws the same line by name: it thanks "all of the surviving Directors of ARPA (the first, Roy W. Johnson, is dead)," a category it explicitly separates from York, Killian, and Admiral John E. Clark, thanked in the same sentence but not as Directors. The report's own chronological list of ARPA directors (Johnson, then Austin W. Betts, then Ruina/Sproull/Herzfeld, then Rechtin, then Lukasik) never includes York, consistent with his later, separate appointment as the first Director of Defense Research and Engineering (claim-herbert-york-first-director-defense-research-engineering-ddre-1958).
This directly resolves a contradiction this vault's own entity-herbert-york hub had carried unresolved since 2026-10-17: a 2017 secondary source calling York "the first full director of DARPA" against institutional sources naming Roy Johnson. This is the first resolution built on York's own first-person testimony rather than a third party's summary. (A Harold Brown/C. Bruce Tarter Physics Today obituary, December 2009, appears to independently confirm the same chief-scientist→DDR&E sequence "in the same words' spirit," but the originating capture recorded no URL or sha for that piece, so it is noted here only as an unverified lead, [unverified-quote — needs URL/sha], and not counted toward this note's roots.)

“And it's no accident, then, that I went from membership on the President's Scientific Advisory Committee to be Chief Scientist of ARPA. Now, that's not simply, though, Killian trying to get one of his people over there. I was not a long time associate of Killian.... I was somebody that Killian thought knew what was necessary, could contribute effectively, and was available — I was all of those things.”
