Ludwik Rajchman's international public-health career ended within a few years via pressure from both Cold War blocs — a US congressional subpoena (Senate Internal Security Subcommittee, not McCarthy's own committee) and a Polish revocation of his passport

Ludwik Rajchman's career as an international public-health administrator — director of the League of Nations Health Organization, then founding chairman of UNICEF — ended not through a single political rupture but, on the available record, through two independent ones in roughly the same years. Per Wikipedia, uncited: "Rajchman was subpoenaed in the McCarthy period: he abruptly left for France and never returned to the United States." Separately, a named-author account from the Minnesota Polish Medical Society states that "his diplomatic passport was revoked by Polish authorities, which effectively brought an end to his illustrious international public health career." Read together, the same man was made unwelcome by Washington's anti-communism and Warsaw's communism within a comparable window — not sequential causes but a pincer from opposite ends of the same Cold War.

The Polish passport-revocation detail is corroborated by a named, Tier 3 source. The American side is now confirmed directly: Rajchman's own FBI file, released via FOIA and read at claim-fbi-file-confirms-siss-subpoenaed-rajchman-february-1957, documents the subpoena in detail — served February 19, 1957, issued over the signature of James O. Eastland as chairman of the Senate Internal Security Subcommittee, a separate body from Joseph McCarthy's own Permanent Subcommittee on Investigations that is often conflated with it under the "McCarthy period" label. The file's own silence after May 1957 corroborates, without proving, that Rajchman never returned to the US (see claim-fbi-file-shows-no-us-contact-with-rajchman-after-1957). A separate, independent Tier 3 account (Josep Lluís Barona, Mètode, 2014) converges on the same 1957 date and is the only source read this session to state outright that the episode ended his public-health career, rather than merely coincided with its end.

• 2026-09-13 — the note originally flagged the US-side leg [unverified-mechanism], resting on an uncited Wikipedia sentence with no corroboration. A direct read of Rajchman's FBI FOIA file (Tier 1) confirms the subpoena and narrows its attribution: issued by the Senate Internal Security Subcommittee under James O. Eastland, not Joseph McCarthy's own subcommittee as the popular "McCarthy period" framing implies.
