Nelson Wilmarth Aldrich was a prominent American politician and a leader of the Republican Party in the United States Senate, where he represented Rhode Island from 1881 to 1911. By the 1890s, he was one of the "Big Four" key Republicans who largely controlled the major decisions of the Senate, along with Orville H. Platt, William B. Allison, and John Coit Spooner. Because of his impact on national politics and central position on the pivotal Senate Finance Committee, he was referred to by the press and public alike as the "general manager of the Nation", dominating tariff and monetary policy in the first decade of the 20th century.
