The Morgan interests had financed the organization of the National Tube Co., the principal figure in which was Edmund C. Converse, so the tube company naturally was taken in. The other concerns and interests which it was proposed to unify into the new corporation were the American Steel & Wire Co., the chief figures in which were the late John Warne Gates, Alfred Clifford, William Edenborn, and others; the four companies forming the so-called Reid-Moore group, controlled by Daniel G. Reid and William H. Moore--namely the National Steel Co., American Tin Plate Co., American Sheet Steel Co., and American Steel Hoop Co. By the early part of February, 1901, the negotiations were concluded and the plans for the organization of the United States Steel Corporation were announced. They provided for the amalgamation of these eight companies, the smallest of which had a capitalization of $33,000,000 and the largest of more than $300,000,000. Before the plans were finally put through, however, two more units were added to the list, the Lake Superior Consolidated Iron Mines, dominated by the Rockefeller interests, and the American Bridge Co., at the head of which was Percival Roberts, Jr. The absorption of the Lake Superior Consolidated Co., with its vast ore holdings and steamship fleet, was deemed necessary to ensure the Steel Corporation an adequate ore reserve. The American Bridge Co., which secured most of its supplies of steel from the Carnegie company, seemed to fit naturally into the plans for the consolidation. Thus there were ten large companies taken in, merged to form the United States Steel Corporation. They had an aggregate capital of $867,550,394, as follows: ===================================================================== COMPANY | COMMON | PREFERRED | STOCK | STOCK --------------------------------------+--------------+--------------- American Bridge Co. | $30,527,800 | $30,527,800 American Sheet Steel Co. | 24,500,000 | 24,500,000 American Steel Hoop Co. | 19,000,000 | 14,000,000 American Steel & Wire Co. | 50,000,000 | 40,000,000 American Tin Plate Co. | 28,000,000 | 18,325,000 Carnegie Steel Co. | 160,000,000 | [A]160,000,000 Federal Steel Co. | 46,484,300 | 53,260,900 Lake Superior Consolidated Iron Mines | 29,424,594 | . . . . . .
