Mises does a great profile of Nicholas Biddle (1786-1844), president of the Second Bank of the United States - the central bank that preceded the Federal Reserve, and provides some useful analogues to not just the current Chairman of the Fed, but to all Fed-friendly crony insitutions that are doing all in the power to perpetuate the hegemony of Wall Street.
Like Ben Bernanke today, Nicholas Biddle cultivated the veneer of a benign civil servant calculating serenely far above the political fray. In reality he, like Bernanke, was up to his neck in the backroom game of power.
