United States. Council of National Defense. Committee on Labor. Section on Industrial Training for the War Emergency

This book is credited to the United States Council of National Defense, Committee on Labor, Section on Industrial Training for the War Emergency rather than to a single personal author. That section was part of the U.S. wartime mobilization effort during World War I, when government agencies were trying to solve severe labor shortages in factories and shipyards.

The section’s publications focused on fast, practical industrial instruction—especially ways to prepare inexperienced workers for specialized jobs needed in war production. In that sense, the "author" is really an official government body speaking in a collective voice, shaped by administrators, educators, and labor advisers working under emergency conditions.

The work is closely connected with the broader early-20th-century vocational education movement in the United States. Contemporary sources about that movement often point to educator Charles Allen Prosser as a major figure in promoting industrial and vocational training, but for this title the named author remains the government section itself, not Prosser as an individual.
