Jack Vinogradov
also: Джек Виноградов, обер-Джек, ober-Jack
An acquaintance of Chekhov and Suvorin's circle known by the nickname "Jack" (Джек) grafted onto the surname Vinogradov -- not otherwise identified by first name/patronymic in this letter. Chekhov reports reading in a "Russkiye Vedomosti" telegram that he has become an "ober-Jack" (обер-Джек), Chekhov's own comic coinage modeled on German-style official rank prefixes (Ober-, as in Oberst, Oberleutnant) grafted onto the nickname to mock the pomposity of the promotion rather than name any real title. Chekhov jokes about how pleased his wife, Yelizaveta Zakharovna, must be, and about his habit of long-winded parenthetical remarks, while affirming he is "the kindest of men." Possibly connected to family:vinogradovs-suvorin-circle, an otherwise-unidentified Vinogradov family already in the corpus (first appearing in) who sent regards alongside Suvorin's household; the surname match is suggestive but not confirmed by any shared first name or other detail, so this entity is kept distinct rather than merged.
