Ivan Goncharov's novel "Oblomov" was published in 1859 and depicted, in its hero, the greatest couch-potato in literature. So appealing is Oblomov's habit of never really getting up that his name has become synonymous with a sort of fatalistic laziness. So prevalent a character trope did Oblomovism become in Russia that Lenin said that three revolutions had not been able to defeat it. Lesley Chamberlain explores the book and its legacy.
