A very clear articulation of the economic history of depression era and lessons (hopefully!!) learned from Christina Romer Chair of Council of Economic Advisors to President Obama.
To quote Economist "Christina Romer... is very fun to listen to. She provides an extremely cheery account of the policy failures and successes of the 1930s."
In addition I would recommend Paul Krugman's "The Return of Depression Economics" to understand global crises since Depression.
