Lolita is nothing if not controversial. Vladimir Nabokov’s “relatives and supporters have rejected a claim that her character was plagiarised from a 1916 novel by a German journalist who went on to support Hitler. Michael Marr, a German literary scholar, suggested that a novella, Lolita, written in 1916 by Heinz von Eschwege, may have provided the foundations for the 1955 Nabokov novel.”
