In the late 1890s, Rockefeller joined fellow Standard Oil principal Henry H. Rogers in forming the Amalgamated Copper Mining Company, a holding company that intended to control the copper industry. Rockefeller, along with Henry Rogers, devised a scheme which earned them a profit of $36 million. First, they purchased Anaconda Properties from Marcus Daly for $39 million, with the understanding that the check was to be deposited in the bank and remain there for a definite time (National City Bank was run by Rockefeller's friends). Rogers and Rockefeller then set up a paper organization, known as the Amalgamated Copper Mining Company, with their own clerks as dummy directors, saying the company was worth $75 million.
