Standard Oil an "unreasonable" monopoly under the Sherman Antitrust Act, Section II. It ordered Standard to break up into 34 independent companies with different boards of directors, the biggest two of the companies were Standard Oil of New Jersey (which became Exxon) and Standard Oil of New York (which became Mobil). Standard's president, John D. Rockefeller, had long since retired from any management role. But, as he owned a quarter of the shares of the resultant companies, and those share values mostly doubled, he emerged from the dissolution as the richest man in the world. The dissolution had actually propelled Rockefeller's personal
Standard Oil company to hold shares in other companies in any state. So, in 1899, the Standard Oil Trust, based at 26 Broadway in New York, was legally reborn as a holding company, the "Standard Oil Co. of New Jersey" (SOCNJ), which held stock in 41 other companies, which controlled other companies, which in turn controlled yet other companies. According to Daniel Yergin in his Pulitzer Prize-winning "" (1990), this conglomerate was seen by the public as all-pervasive, controlled by a select group of directors, and completely unaccountable. In 1904, Standard controlled 91 percent of production and 85 percent of final sales.
