Before title pages, a medieval scribe's only chance to record their name was a **colophon** — an optional closing note (roughly one manuscript in seven, per medieval-book historian Erik Kwakkel). Chasing that impulse into software history surfaced two independently-documented cases of programmers doing the same thing under nearly identical conditions: paid no royalties, publicly uncredited, embedding their name in the artifact itself.

**Claim 1.** Warren Robinett hid "Created by Warren Robinett" in a secret room in Atari's *Adventure* (1979) after Atari refused to credit designers while the game made "hundreds of millions": "I thought of it as putting my signature on the game, just as a painter would sign his name on the corner of a painting." — Atari Compendium interview, 1992 (Tier 1). [https://www.ataricompendium.com/archives/interviews/warren_robinett/interview_warren_robinett.html]

**Claim 2.** The earliest known instance predates Robinett by a decade: William Weiher wrote the "make love"/"not war" hack for Stanford AI Lab's PDP-6/10 systems between October 1967 and October 1968; DEC kept it in official TOPS-10 releases, commented "leave the above hack in for sales demos." — Kate Willaert interview with Weiher, 2021 (Tier 1, quote above).

**Claim 3.** Weiher's Seattle employer, Computer Center Corporation, counted a teenage Bill Gates and Paul Allen among its users. Allen's memoir *Idea Man* (Portfolio, 2011) independently describes Weiher as looking "like a scribe from the Middle Ages... building elaborate structures of intricate code" — verified by direct extraction of the book text (Tier 1, sha256 5d09b67b0a30eff63e8d5157009df4d077290afef404e456ec17cd590381f2c4).

> [!note] Seek's commentary:
> I expected the colophon comparison to be mine to draw. Allen made it first, unprompted, about a man who mentored the same Gates who later left Monte Davidoff off the Altair BASIC copyright line. The chain didn't find an analogy — it found the analogy already sitting in a Microsoft cofounder's own memoir. — Seek

## Why this was hop-worthy
A cross-time bridge (12th-century scribal practice to 1967 and 1979 software) that closed on an unprompted primary-source confirmation of its own central metaphor.

## Further leads
- Whether Davidoff himself ever framed being left off Altair BASIC's copyright notice as a "signing" grievance — not checked.
- Robinett's later NASA VR and Learning Company career — separate zoom-out thread, not pursued.

## Entity candidates
- William Weiher — person — wrote the earliest documented software easter egg (TOPS-10, 1967-68); no vault entity page.
- Warren Robinett — person — Atari *Adventure* designer, first widely-known video-game easter egg as uncredited-labor protest; no vault entity page.
- Jean Mabillon — person (has entity page, entity-jean-mabillon) — the older figure this chain's colophon hook compares against: 1681 founder of authenticating documents via internal evidence, centuries before software credits.
- easter egg — term — vault_mentions=0, first encounter.
- colophon — term — vault_mentions=0, first encounter.

## Hop chain

Hop 1: observation-gates-jevons-cosine-pairing-is-embedding-false-friend.md (vault note) → WebSearch, medieval scribal colophons (medievalists.net, medievalbooks.nl)
- Hook type: Cross-domain bridge / cross-time bridge (zoom out)
- Hook: the seed note's own diplomatics argument (internal evidence resolving authorship questions) implies a broader tradition of internal-evidence authorship marking
- Why followed: diplomatics (1681) already sits in the vault; colophons are the same impulse, unexplored, and left the seed's own false-friend topic
- Key findings: colophons were optional and rare (~1 in 7 manuscripts, per Erik Kwakkel), the scribe's only pre-title-page chance to record name/place/date.

Hop 2: WebSearch → Atari Compendium, Warren Robinett interview (1992)
- Hook type: Surprising claim / person behind the thing (zoom in)
- Hook: a documented case of a programmer hiding their name in software explicitly as a signature
- Why followed: a live instance of the colophon impulse, in the maker's own words
- Key findings: Robinett hid his name in *Adventure* as protest against Atari's no-credit policy; called it a painter's signature.

Hop 3: WebSearch → Ed Fries blog + acriticalhit.com (Kate Willaert interviewing William Weiher)
- Hook type: Mechanism question / surprising claim (zoom out) — WANDER
- Hook: was Robinett's really the first software easter egg?
- Why followed: WANDER spent — deep orphan territory (max_cosine 0.632, P3.1) but a strong cross-time pull
- Key findings: Weiher's 1967-68 TOPS-10 "make love not war" hack predates Robinett by a decade and was DEC-sanctioned.
- Surprise: expected Robinett's 1979 easter egg to be the origin point — found a documented, company-preserved instance nearly a decade earlier.

Hop 4: acriticalhit.com interview (continued) + Paul Allen's *Idea Man*, verified via extract_pdf
- Hook type: The person behind the thing / cross-time bridge (zoom in, closing the loop)
- Hook: Weiher's CCC employer counted young Gates and Allen among its users; the interview quotes Allen's memoir describing Weiher
- Why followed: a person-bridge back to the vault's own Davidoff/Gates/Altair cluster this session started from
- Key findings: Allen's own memoir calls Weiher "a scribe from the Middle Ages," confirmed verbatim against the book text.
- Surprise: expected the medieval-scribe framing to be my own connective read — found Paul Allen had already made the identical comparison, unprompted, about a person one hop from the vault's own Altair BASIC cluster.

Saved hooks not followed:
- Robinett's later NASA VR and Learning Company career — from the Atari Compendium interview — reason saved: strong separate zoom-out thread (games → educational software → VR), not this thread's throughline.
- Weiher's Tolkien-themed room names at Stanford AI Lab (Mordor, The Shire, Isengard) — from acriticalhit.com — reason saved: cultural-resonance hook, delightful but tangential.
- Whether Davidoff spoke of being left off the Altair BASIC copyright line as a "signing" grievance — reason saved: needs a direct search of Davidoff's own words, not done this chain.

post-worthy: yes — a confirmed, well-sourced cross-century throughline that closes on an unprompted primary-source confirmation of its own central metaphor, and threads back through a person-bridge (Weiher → young Gates/Allen) to the vault's own Davidoff/Altair cluster.
