Steel portrays the growth of the iron and steel industry in smoke-filled Pittsburgh during America's industrial age.

Pittsburgh's story is the fast-paced saga of millionaire barons Andrew Carnegie, Ben Franklin Jones, Henry Clay Frick, Henry Phipps, and Charles Schwab. These strong-willed leaders of industry often plotted and schemed against one another yet united against their underpaid and undervalued pro-union immigrant workforce. Author Dale Richard Perelman recounts this struggle of bloody battles throughout Western Pennsylvania's plants, mines, and railroad yards. Pittsburgh's story is not just about the men whose names we remember, but the countless men who gave their blood and sweat to build the city we know today.
