Jack Dennis

MIT professor emeritus and pioneer of dataflow computation — models of computation where an instruction executes when its data becomes available rather than by a sequential program counter — who led MIT's Computation Structures Group from 1963 to 1985; he died in 2026 at 94 (MIT News obituary, 2026-04-10). Matters to this vault as the implicit "common ancestor" candidate for two mid-1980s visual-dataflow environments, LabVIEW and Max: multiple claim-notes ask whether either system's inventors knew of or cited his academic dataflow lineage. So far neither side shows a direct citation — Puckette's own retrospective essay names no dataflow ancestor at all (claim-puckette-max-origins-cite-no-dataflow-ancestor), and a citation-graph lookup on Kodosky's HOPL IV paper (still unread at primary) does not list Dennis's foundational 1975 paper either (claim-kodosky-hopl-reference-list-omits-dennis-citation-unverified-mechanism) — though neither finding is conclusive on its own.

• 2026-08-15: the Kodosky-side block on reading his own HOPL IV paper is now a confirmed standing condition, not a stale gap — checked across three sessions (2026-08-12, 2026-08-14, 2026-08-15) via every fetch route, and this session additionally confirmed via the HOPL IV proceedings table of contents that no alternate, non-paywalled host exists for any paper in the volume. Also newly named: the Dennis-ancestry question and the Brooks/Dreyfus lineage question run the identical vault method (the argument from silence) at opposite ends of its evidentiary-strength range.
