Lolita is a 1955 novel written by Russian-American novelist Vladimir Nabokov. The novel is notable for its controversial subject: the protagonist and unreliable narrator, a middle-aged literature professor under the pseudonym Humbert Humbert, is obsessed with a 12-year-old girl, Dolores Haze, with whom he becomes sexually involved after he becomes her stepfather. "Lolita" is his private nickname for Dolores. The novel was originally written in English and first published in Paris in 1955 by Olympia Press. Later it was translated into Russian by Nabokov himself and published in New York City in 1967 by Phaedra Publishers.
Lolita quickly attained a classic status. The novel was adapted into a film by Stanley Kubrick in 1962, and another film by Adrian Lyne in 1997. It has also been adapted several times for the stage and has been the subject of two operas, two ballets, and an acclaimed but commercially unsuccessful Broadway musical. Its assimilation into popular culture is such that the name "Lolita" has been used to imply that a young girl is sexually precocious. Many authors consider it the greatest work of the 20th century, and it has been included in several lists of best books, such as Time's List of the 100 Best Novels, Le Monde's 100 Books of the Century, Bokklubben World Library, Modern Library's 100 Best Novels, and The Big Read.
