The Rothschilds' role in Anaconda was brief. In 1899, Daly teamed up with two directors of Standard Oil to create the giant Amalgamated Copper Mining Company, one of the largest trusts of the early 20th century. The leading roles in the takeover were played by Henry Huttleston Rogers (John D. Rockefeller's friend and a key man in his Standard Oil businesses) and William Rockefeller (John's brother). They were aided by company promoter Thomas W. Lawson. Although Rogers and William Rockefeller were Standard Oil directors, the company of Standard Oil did not have a stake in this business, nor did its founder and head, John D. Rockefeller, who disliked such stock promotions.
