source_quote: "1950 The Cold War intensifies. In the Eastern bloc, Rajchman is suspected of being a pro-American agent and his Polish diplomatic passport is confiscated: he recuperated his papers only after Stalin's death, in 1956. In the United States, the McCarthyists accuse Rajchman of being a commuist spy: in 1957, he is obliged to leave the country precipitously and never returns, settling permanently in France."

Historical/biographical dating claim; each individual source is Tier 3, but sources.md's floor for historical/biographical claims accepts Tier 3-4 when uncontested, and the point of this note is specifically that three sources independent of each other, of Wikipedia, and of the FBI file converge — which is stronger than any one of them alone. Two of the three (Institut Pasteur, CEU Press blurb) draw on Balinska's biography without citing each other; the third (Barona) is a named historian citing Balinska in his own bibliography. No [unverified-*] flag applies to the convergence itself. Not independently re-checked by a second model."

Three sources, each citing or drawing on [[entity-ludwik-rajchman|Ludwik
Rajchman]]'s biographer [[entity-marta-aleksandra-balinska|Marta A.
Balinska]] but independent of each other, of Wikipedia, and of the FBI's
own surveillance file, converge on the same year and the same outcome
that [[claim-fbi-file-confirms-siss-subpoenaed-rajchman-february-1957]]
and [[claim-fbi-file-shows-no-us-contact-with-rajchman-after-1957]]
establish from the US government's own paper trail:

- The Institut Pasteur's own archival chronology of Rajchman, citing
  Balinska's biography as its documentary reference, states: "in 1957, he
  is obliged to leave the country precipitously and never returns,
  settling permanently in France."
- Historian [[entity-josep-lluis-barona-vilar|Josep Lluís Barona Vilar]],
  in a 2021 biographical essay listing Balinska's biography among its
  sources, writes: "In 1957 he was forced to leave America and never
  returned, settling permanently in France."
- Central European University Press's own description of Balinska's book,
  reproduced on its Google Books listing, states Rajchman "was forced by
  McCarthyism to flee the U.S."

Barona had already published closely related wording on the same episode
in *Mètode* (2014), cited in
[[claim-ludwik-rajchman-squeezed-out-by-both-cold-war-blocs]] — his two
pieces likely share text and are not fully independent of each other, only
of the other two sources here. With that caveat, this is corroboration of
the year and the outcome from a source lineage entirely outside the US
surveillance record: the family biography and the academic literature
that cites it, agreeing with the FBI file's own February 1957 subpoena
date and its silence after May 1957.
