Dneprostroi, a dam and power plant that was one of the most monumental construction projects of the Bolshevik's First Five Year Plan, was a milestone in American-Soviet co-operation. As the largest earth dam in Europe in the 1930s, it represented the first of the giant projects so favoured by Stalin. Anne Rassweiler's informative history of this project reveals new aspects of the struggle between Trotsky and Stalin, the debate on the use of foreign technology, and the effects of collectivization on the industrial projects of the First Five Year Plan. Her study also provides insight into the entry of women into the industrial work force and interaction between party leaders, party membership, and enterprise officials as they sought to realize one of the most ambitious projects in Soviet history.
