Kern was one of many liaisons in Pushkin's life and she would not have become the most famous of his mistresses were it not for the poem that Pushkin put between the pages of the second canto of Eugene Onegin which he presented to her on the day of their parting.
Kern a fost una din multele aventuri din viața lui Pushkin, și nu ar fi devenit cea mai faimoasă dintre amantele lui, dacă nu ar fi fost poemul pus de Pushkin între paginile celui de-al doilea canto al lui Eugene Onegin, pe care i l-a prezentat in ziua despărțirii lor.
