[[claim-ludwik-rajchman-squeezed-out-by-both-cold-war-blocs]] rests its US-side
leg — "Rajchman was subpoenaed in the McCarthy period: he abruptly left for
France and never returned to the United States" — on a single, uncited
sentence in Wikipedia's "Ludwik Rajchman" article. The claim is a specific
historical mechanism (a subpoena, prompting a permanent departure), and the
sourcing floor for a contested or load-bearing mechanism claim is Tier 1–2.
No second source or primary document corroborates it this session. Flagged
`[unverified-mechanism]`.

## Why it matters
The note's actual finding — that Rajchman's career ended via pressure from
*both* Cold War blocs in the same narrow window — depends on this leg being
true. The Polish-side leg (passport revocation) is independently and
credibly sourced; if the McCarthy leg turns out to be wrong, exaggerated, or
conflated with a different event, the "squeezed from both sides" claim
collapses into a one-sided (Polish) story, which is a materially different
and less striking finding.

## What would answer it
- An FBI file on Ludwik Rajchman, reportedly held at
  `archive.org/details/ludwik-rajchman` — unreachable at capture time
  (502/timeout, three attempts). Would confirm or disconfirm the subpoena
  directly if read.
- Marta A. Balinska, *For the Good of Humanity: Ludwik Rajchman, Medical
  Statesman* (CEU Press, 1998) — the definitive biography, unread by this
  vault; likely covers the circumstances of his final departure from the
  US in detail.
- Congressional subpoena/hearing records from the McCarthy period (Senate
  Permanent Subcommittee on Investigations, or House Un-American Activities
  Committee), if Rajchman is named in either.

## Candidate next moves
- Retry the archive.org FBI-file URL in a future session (transient
  failures — 502/timeout — rather than a confirmed block).
- Search HathiTrust or a library catalog for the Balinska biography and
  read the relevant chapter directly.
- Search congress.gov or archive.org's own hearing-transcript holdings for
  "Rajchman" in McCarthy-era subcommittee records.
