Ann Hardy's own testimony in both confirms she wrote/rewrote the SDS-940 OS and confirms, in her own words years apart, that colleagues (including via her husband's own hiring) misattributed that work to Norman — the misattribution *episode* is now Tier-1 confirmed. The *specific* disclaimer quote below ('I don't know anything about the operating system...') was NOT found, verbatim or in substance, in either transcript — the flag narrows to that one sentence, not the whole claim.

Ann Hardy wrote the operating system for Tymshare's SDS 940 timesharing
service in the 1960s–70s and rose to become a Tymshare vice president.
According to the Computer History Museum's retelling of its own
oral-history material, colleagues believed her husband, [[entity-norman-hardy|Norman Hardy]], had
written the operating system she actually authored — and he reportedly had
to correct them directly: "I don't know anything about the operating system.
I've never looked at the code."

The CHM blog surrounds the claim with corroborating detail on a culture that
discounted her actual authority: a pay gap (misattributed by the 2026-07-09
audit to her earlier IBM years) that a 2026-07-23 verification session's
direct read of the CHM 2016 primary oral history instead pins to 1967
Tymshare stock options — Ann Hardy states Tymshare gave her "very few," "less
than half of what they gave any of the men, even though some of the men were
essentially working for me," with cofounder Dave Schmidt's stated reason
being that options "would tempt a woman to continue to work instead of stay
home and have children." The capture also notes that IEEE Spectrum
republished the account independently (not independently re-checked this
session).

**Flag — `[unverified — needs primary oral-history text]`.** This is a
surprising, load-bearing biographical claim, and the sourcing floor
(`00-meta/sources.md`) escalates surprising/contested biographical claims to
Tier 1–2 primary. The Tier-2 CHM blog is an institutional *retelling* of the
museum's oral-history archive; the raw oral-history transcript — where the
disclaimer quote would live verbatim — was not read at capture. The exact
attribution is routed for verification:
[[question-verify-ann-hardy-os-credit-primary-oral-history]]. The note stays
`status: seedling` until that primary is read.

**Update, 2026-07-23:** two independent primary transcripts have now been
read in full (see `audit_status` above and
[[claim-norman-hardy-tymnet-account-confirms-ann-hardy-wrote-os]] for
Norman Hardy's own independent corroboration). The misattribution *episode*
is Tier-1 confirmed in Ann Hardy's own words, twice, years apart. The flag
now narrows specifically to the exact disclaimer sentence attributed to
Norman Hardy, which does not appear, verbatim or in substance, in either
transcript read — the note stays `seedling` on that narrower ground, not the
broader one.

The structural interest is that this is a *credit-misattribution* case in a
new domain for the vault. Its existing cluster on the topic —
[[claim-linnainmaa-priority-not-paternity]], [[backpropagation-gap]],
[[myth-werbos-invented-backpropagation]] — concerns *algorithmic priority*:
who first derived a method. This case concerns *authorship credit for built
work*, misdirected along a gender line to a spouse. Same failure mode (the
wrong name attached to real work), different mechanism.
