Railroad apprentice who transplanted railroad management
Carnegie rose from telegraph messenger to superintendent of the Pennsylvania Railroad's western division under Thomas Scott and J. Edgar Thomson. There he absorbed the railroad's system of detailed cost reporting, hierarchical control and relentless throughput. When he opened the Edgar Thomson Works in 1875, named partly to court the railroad as a buyer, he applied those same methods to making Bessemer steel rails, and his competitive edge came from management borrowed from the railroads rather than from any metallurgical invention.
