All three exemplars confirmed against the OCR'd primary, including Avery as 'only one of many premature discoveries in the history of science', the Hershey-Chase bridge ('connect their conclusion that DNA is the genetic material with canonical knowledge'), Avery as 'in some respects … a more dramatic example of prematurity than Mendel's', and Polanyi's 1914–1916 adsorption theory held 'so ridiculous by the leading authorities of the time' and 'rediscovered only in the 1950's'. CORRECTED (quote integrity): source_quote previously read 'Mendel's discovery of the gene ... made no immediate impact, it can be argued, because…' — the words 'of the gene' are not in that sentence; they were bridged in by ellipsis from the preceding clause ('whose discovery of the gene in 1865 had to wait 35 years'). Replaced with the unspliced verbatim sentence. The body's rendering was already correct (it kept 'discovery of the gene' outside the quotation marks), so no claim changes. CORRECTED (precision): body now says 'three named *retrospective* exemplars' — the essay carries five worked prematurity examples in total, the other two being the prospective here-and-now cases, so the unqualified 'three' could read as exhaustive against the sibling note.

In his 1972 *Scientific American* essay, Gunther Stent illustrates his criterion of
[[claim-stent-prematurity-covers-neglected-not-contested-ideas|prematurity]] with three
named *retrospective* exemplars, and all three share one shape: an empirically correct finding, not
contested in retrospect, whose acceptance was delayed until the surrounding "canonical
knowledge" caught up.

- **Oswald Avery's 1944** identification of DNA as the bacterial transforming principle
  is the central case — "only one of many premature discoveries in the history of
  science," in Stent's words. It became connectable to canonical knowledge only after
  Hershey and Chase's 1952 phage experiment, which let the field "connect their
  conclusion that DNA is the genetic material with canonical knowledge."
- **Gregor Mendel's 1865** discovery of the gene "made no immediate impact, it can be
  argued, because the concept of discrete hereditary units could not be connected with
  canonical knowledge of anatomy and physiology in the middle of the 19th century" —
  resolved once chromosomes and mitosis/meiosis were understood by 1900. Stent judges
  Avery's case "in some respects ... a more dramatic example of prematurity than
  Mendel's."
- **Michael Polanyi's 1914–1916** gas-adsorption theory, dismissed as "ridiculous" by
  contemporary authorities, became conceivable only after 1930s quantum-mechanical
  resonance theory, and was "rediscovered ... in the 1950's" — the one exemplar drawn
  from outside biology.

These vindicated cases are why the vault's inherited scope condition ("correct-but-
neglected, not contested") reads naturally onto Stent — but they are the concept's
*paradigm* instances, not its full scope. Stent's own text also applies prematurity
prospectively to claims of unknown truth value
([[claim-stent-here-and-now-prematurity-covers-unresolved-claims]]). All three
exemplars belong to the vault's delayed-vindication cluster alongside
[[claim-jeffress-1948-place-theory-waited-decades-for-anatomical-confirmation]],
[[claim-neural-circuit-theories-wait-decades-for-anatomical-confirmation]], and
[[claim-lamport-paxos-greek-allegory-delayed-publication]], and their qualitative
"had to wait" pattern is the one the bibliometric
[[claim-sleeping-beauties-delayed-recognition-is-a-continuum]] later finds has no
sharp threshold.

> [!note] Seek's commentary:
> These are the cases that make Stent's criterion feel clean, and they're worth
> pinning as their own note precisely because they're the evidence *for* the narrow
> reading — the reading the here-and-now finding then complicates. Keeping the two
> notes separate lets a reader see the tension directly: the exemplars fit the
> vindicated-only story, and the concept doesn't. The Avery→Hershey-Chase→canonical

> actually means operationally — a finding waiting not for more evidence but for a
> conceptual bridge. — Seek
