title: "Pesch & Plail's 2009 and 2012 retellings of Boltyanskii's naming-pressure testimony agree closely — self-consistency across two venues, not independent corroboration"

source_quote: "Boltyanskii claimed the version of the maximum principle as a necessary condition to be his own contribution and described how Pontryagin hampered his publication. He said Pontryagin intended to publish the results under the name of four authors. After Boltyanskii refused to do so, he was allowed to publish his results in 1958 but said that he had to praise Pontryagin's contribution disproportionally and had to call the principle Pontryagin's maximum principle."
source_quote_2: "According to Boltyanskii, Rozonoér, an engineer, was encouraged to publish a tripartite work on the maximum principle in Avtomatika i Telemekhanika in 1959, in order to disseminate the knowledge of the maximum principle in engineering circles and to contribute this way to the honour of Pontryagin as discoverer of the maximum principle."

Boltyanskii, \"The Maximum Principle — How it came to be?\", DFG Schwerpunktprogramm Report No. 526, TU München, 1994) — unread by this vault; both the 2009 and 2012 tellings trace to the same two authors and, presumably, the same underlying 1994 account. The 2012 paper's own reference list does not re-cite the 1994 report; it points the reader back to the 2009 paper instead."

[[entity-hans-josef-pesch|Pesch]] & Plail published a second account of [[entity-v-g-boltyanskii|Boltyanskii]]'s naming-pressure testimony three years after their 2009 *Control and Cybernetics* survey, this time in *Documenta Mathematica*'s *Optimization Stories* volume. The 2012 version matches the substance of [[claim-boltyanskii-testimony-locates-pontryagin-naming-convention-in-internal-soviet-pressure|the 2009 account already in this vault]] almost word for word — Pontryagin "hampered" Boltyanskii's publication and intended to credit it to four authors; Boltyanskii was allowed to publish in 1958 only after agreeing to praise Pontryagin's contribution and to call the result Pontryagin's maximum principle. The only wording differences are "praise" for "appreciate," and the 2012 telling drops the 2009 detail that Boltyanskii also had to cite McShane's needle variations. In exchange, the 2012 telling adds a detail absent from 2009: per Boltyanskii, [[entity-rozonoer|Rozonoér]], a Soviet engineer, was specifically encouraged to publish a 1959 tripartite paper on the maximum principle in *Avtomatika i Telemekhanika*, to spread Pontryagin's name as discoverer into engineering circles.

This is evidence of the authors' own consistency across two publications in two journals three years apart — not independent corroboration of the underlying 1994 testimony, since both tellings trace to the same two historians and, so far as either paper's own reference list shows, the same source. What it rules out is that Pesch & Plail softened, altered, or walked back the account between 2009 and 2012; what it does not do is confirm the account against Boltyanskii's own words, which this vault still has not read (see [[question-verify-boltyanskii-1994-primary-naming-pressure-testimony]]).

> [!note] Seek's commentary:
> Two tellings, three years apart, in two different venues, and the second one doesn't retreat an inch — it adds a name instead. That's the kind of consistency that would reassure me about a witness in a courtroom. It reassures me somewhat less here, because the two tellings share a author line, not a courtroom. Same storyteller, same story, told twice. I still want to hear it from Boltyanskii.
