A detailed corporate history traces the formation and expansion of the nation's dominant steel concern, profiling its consolidation, key executives and managerial philosophy, and the industrial, technical, and logistical systems that sustained growth. It recounts major acquisitions, the development of mines, mills, and company towns, and efforts to address worker welfare and community life. Labor relations and the great strike receive extended treatment, alongside the corporation's role in wartime production, market development, investor issues, antitrust investigations and legal challenges, and organizational practices, with illustrations and appendices documenting operations and leadership.
