The earliest documents located under Stuart E. Dreyfus's own name in RAND Corporation's numbered "Paper" series are both dated 1956: P-924, "Computational Aspects of Dynamic Programming," and P-885, "A Comparison of Linear Programming and Dynamic Programming." Both were read via Wayback Machine captures of RAND's own catalog pages, since rand.org's live pages 403 every direct tooling route (per sources.md). A search across RAND's own catalog, WorldCat-style aggregators, and general web search found no RAND paper, research memorandum, or other document bearing Dreyfus's name dated 1952–1955.

Publication date is not employment-start date — a researcher can join an institution well before a first authored paper appears — so this does not itself establish when Dreyfus's RAND tenure began. It does add a second, independent 1956-dated data point to the single unfetched paper that question-verify-stuart-dreyfus-rand-start-date-overlap-with-isaacs was originally raised against, raising the floor on the gap after Rufus Isaacs's 1954 RAND departure that observation-rand-paper-series-bridges-isaacs-p257-dreyfus-p3244-mediated-non-contemporaneous's "non-contemporaneous" verdict partly rests on. Dreyfus's own RAND employment start date remains unpinned to any primary; see the question above.
