The surname of the male protagonist in Anton Chekhov's The Lady with the Dog is Gurov. His full name is Dmitri Dmitrich Gurov, a married Moscow banker who meets Anna Sergeyevna while both are vacationing in Yalta.
At first, Gurov treats the relationship as a temporary affair, reflecting his boredom and his experience with women. The story gradually overturns that expectation: after returning to Moscow, he finds himself unable to forget Anna and travels to Saratov to see her again. Their relationship becomes emotionally serious, even though both remain trapped in unhappy marriages.
Chekhov published the story in 1899, and it is widely regarded as one of his finest works. A frequent mix-up is associating Gurov with other famous Russian literary figures: Raskolnikov belongs to Crime and Punishment, Oblomov to Ivan Goncharov's novel, and Onegin to Pushkin's Eugene Onegin.
