Adam Johann von Krusenstern
Krusenstern
also: Крузенштерн, Иван Фёдорович Крузенштерн, Kruzenshtern
Russian navigator and explorer (1770-1846), leader of the first Russian circumnavigation of the globe. Chekhov thanks Suvorin here for a gift or loan of a book by or about him ("Крузенштерна"), presumably relevant to his own upcoming journey to Sakhalin, and briefly praises the writing.
