Central banks in Great Britain and the United States arose early in the financial revolution. The Bank of England was created in 1694 while the first Banks of the United States appeared in 1791-1811 and 1816-36, and were followed by the Independent Treasury, 1846-1914. These institutions, together with the Suffolk Bank and the New York Clearing House, exercised important central banking function before the creation of the Federal Reserve System in 1913. Significant monetary changes in the lives of these British and American institutions are examined within a framework that deals with the knowledge and behavior of central bankers and their interactions with economists and politicians. Central Bankers' behavior has shown considerable continuity in the influence of incentives and their interest in the stability of the financial markets.
