Past financial crises

When financial markets are in turmoil, I like to link to my articles about how Alexander Hamilton and J.P. Morgan dealt with financial crises past. Not so much that the specific measures they took carry great relevance for the situation today (though they did innovate a lot of what public and private decisionmakers have used in financial crises since); it's more that they exemplify the serious but calm state of mind needed when you face such things.
