The fifth volume of Mikhail Vostryshev's series is dedicated to the time of industrialization, when the main values ​​were labor and personnel capable of solving key problems in the construction of a socialist state. Despite a half-starved existence, the people of the country worked tirelessly to increase productivity and set new records. During this period, technical backwardness began to be overcome: domestic machine tools, transport and powerful factories appeared. Industrial transformations changed the social structure: many young peasants became workers, which opened a new era for Soviet science, culture and education. The book describes how these efforts laid the foundation for large-scale achievements in the future, making it an indispensable guide to one of the key periods in the history of the USSR.
