The book tells about Russian engineers who emigrated to America during the Russian Civil War (1918-1922) or after the end of World War II. The author provides biographical details of both those who were widely known for their developments and discoveries, and those who contributed to the economic prosperity of the United States with qualified and conscientious work. Archival documents from the Museum of Russian Culture (San Francisco), materials from the Russian-language press in the United States, as well as publications by the engineers themselves were used.
