fueled growing public attacks on Standard Oil and monopolies in general. Her work was published in 19 parts in McClure's magazine from November 1902 to October 1904, then in 1904 as the book The History of the Standard Oil Co. The Standard Oil Trust was controlled by a small group of families. Rockefeller stated in 1910: "I think it is true that the Pratt family, the Payne–Whitney family (which were one, as all the stock came from Colonel Payne), the Harkness-Flagler family (which came into the company together) and the Rockefeller family controlled a majority of the stock during all the history of the company up to the present time." These families reinvested most of the dividends in other industries, especially railroads. They also invested heavily in the gas and the electric lighting business (including the giant Consolidated Gas Co. of New York City). They made large purchases of stock in U.S. Steel, Amalgamated Copper, and even Corn Products Refining Co. Weetman Pearson, a British petroleum entrepreneur in Mexico, began negotiating with Standard Oil in 1912–13 to sell his "El Aguila" oil company, since Pearson was no longer bound to promises to the Porfirio Díaz regime (1876–1911) to not to sell to U.S. interests. However, the deal fell through and the firm was sold to Royal Dutch Shell. In China Standard Oil's production increased so rapidly it soon exceeded U.S. demand and the company began viewing export markets. In the 1890s, Standard Oil began marketing kerosene to China's large population of close to 400 million as lamp fuel. For its Chinese trademark and brand, Standard Oil adopted the name Mei Foo (), (which translates to Mobil). Mei Foo also became the name of the tin lamp that Standard Oil produced and gave away or sold cheaply to Chinese farmers, encouraging them to switch from vegetable oil to kerosene. The response was positive, sales boomed and China became Standard Oil's largest market in Asia. Prior to Pearl Harbor, Stanvac was the largest single U.S. investment in Southeast Asia. The North China Department of Socony (Standard Oil Company of New York) operated a subsidiary called Socony River and Coastal Fleet, North Coast Division, which became the North China Division of Stanvac (Standard Vacuum Oil Company) after that company was formed in 1933. To distribute its products, Standard Oil constructed storage tanks, canneries (bulk oil from large ocean tankers was re-packaged into tins),
