Marshak had a prolific career in children's literature. Soviet critic Viktor Shklovsky wrote that "Samuil Marshak understood that many new writers would appear in the new Soviet republic. He stood at the door of literature, a benevolent angel, armed not with a sword or with a pencil, but with words on work and inspiration." Marshak's contributions to the field of children's literature was not just limited to his own writings. In 1924, he became the head of the children's branch of the state publishing house Gosizdat (GIZ), a position he held for over a decade. Through his role as editor, Marshak attracted some of Russia's best writers to try their hand at writing for children, including Evgeniy Shvarts and OBERIU member Daniil Kharms.
