A deep believer in the progressive themes of efficiency and scientific expertise, Aldrich led a team of experts to study the European national banks, discovering that Britain, Germany and France had a much superior central banking system. He worked with his experts to design a plan for an American central bank in 1911. In 1913 Woodrow Wilson adopted Aldrich's plan and implemented it as the Federal Reserve system.
Because of his control of the Senate (and his daughter Abby Greene Aldrich's marriage to John D. Rockefeller, Jr.) Aldrich is considered to have been one of the most powerful politicians at the time. His grandson and namesake Nelson Aldrich Rockefeller became one of the most powerful politicians of a later era and served a stint as Vice President of the United States. He died on April 16, 1915, in New York, New York, and was buried in Swan Point Cemetery in Providence, Providence County, Rhode Island.
