Stefan Savvich Krivtsov (Russian: Степан Саввич Кривцов; 1885–1943) was a Russian Soviet professor of history and cultural activist who played a major part in the ideological development of the Proletkult.
He graduated from the Faculty of History, Physics and Mathematics, Moscow State University.
[1] He saw the role of Proletkult as being involved in life-building: "The Proletkult is striving to create a new proletarian culture, not just new songs, new music, new theatre, but rather a whole new mode of life.
[2] He wrote for Proletarskaya Kul'tura, often critically when the reality of the movement did not live up to his vision.
In 1928, following the death of Alexander Bogdanov, Krivtsov wrote an account of his memories of one of the founding figures of Proletkult for the Under the Banner of Marxism.
