In order to get a true perspective on the events immediately leading up to the formation of the United States Steel Corporation, it is necessary to review briefly the history of the steel industry in the United States during the latter half of the nineteenth century, and especially during its closing decade. In a short half century steel making in America had grown from the age of swaddling clothes to full manhood, or rather gianthood. It stood supreme among industries. From being unimportant among the iron and steel producing nations, the United States, in a comparatively few years, had forged its way to the first place. Its steel mills turned out nearly half of the hard metal used by the world. Steel, from being an industry composed of a few scattered mills situated as nearly as possible to ore deposits with little regard to markets, had become one consisting of great corporate entities each made up of many plants, and these had in their service railroads and steamships plying to and from ore fields situated sometimes hundreds of miles from the plants, bringing to the mills such quantities of the raw metal as but a short time before had not been known to exist. It had bent to its use every modern invention, the newest discoveries of science. Fortunes had been spent, won, and lost in building up these great structures. It had at the same time been an industry subject to the most amazing fluctuations, periods of feast being followed closely by periods of famine. This half century, or the last two decades of it, was, as has been suggested, a period of war to the hilt between manufacturer and manufacturer, war in which no quarter was asked or given. The history of the steel industry in America bristles thick with the names of millionaires who worked their way to fortune from the slag pile. And for every one of these there were many, whose names are forgotten, who sacrificed health, strength, and fortune in the mad fight for the wealth that poured in unstinted stream from the glowing furnaces of molten iron. The law of steel was essentially that of the survival of the fittest.
