America’s Top Companies: 1917
A full 40% of America’s largest companies, as ranked by assets, are oil, steel or mining companies, including many descendants of John D. Rockefeller’s Standard Oil, which was broken up only six years earlier. But the era of the trust lingers. The nation’s largest company is Andrew Carnegie’s U.S. Steel, which the government unsuccessfully tried to break up in 1911. U.S. Steel has assets of $2.5 billion (around $47 billion in today’s dollars) and is more than three times larger than the country’s second-largest firm, AT&T. Other trusts also feature prominently: Central Leather, American Tobacco, U.S. Rubber and J.P. Morgan’s International Mercantile Marine.
