Boris Stepanovich Zhitkov (Russian: Бори́с Степа́нович Житко́в) (11 September 1882 — 19 October 1938) was a Russian author, mainly of children's books.
Zhitkov was born in Novgorod; his father was a mathematics teacher and his mother a pianist. His works include numerous books in which he, in a figurative form, described various professions. His books are based on his rich experience as a sailor, ship captain, scientist, traveler and explorer. Between 1916 and 1924 he was a sailor and, later, a ship's captain. He also worked as a navigator, an ichthyologist, a metal worker, a shipbuilding engineer, a teacher of physics and drafting, and a technical college headmaster.
In 1924 Zhitkov started to be published and soon became a professional writer. He is best known for the hugely successful children's travel book What I Saw (Russian: Что я видел) about the summer vacation adventures of a curious little boy nicknamed Pochemuchka. He was a close friend of Korney Chukovsky, who wrote in his diary entry for 28 December, 1931:
Zhitkov is all upset about the self-flagellation going on among critics at the Writers' Union. He says that at the meeting where Eikhenbaum was asked to practice self-criticism, Eikhenbaum responded, "Self-criticism should be practiced before one writes, not after." Zhitkov's interpretation of the now famous meeting runs as follows: "We're all just so many sons of bitches, so let's pull down our pants and let ourselves be whipped."
Zhitkov's 1941 historical novel about the 1905 Revolution, Viktor Vavich (Russian: Виктор Вавич), was immediately destroyed and republished in 1999 only thanks to Lydia Chukovskaya having saved a copy; Boris Pasternak called it "the best thing that has ever been written about 1905; it's shameful that nobody knows this book."
