Timothy Franz "Great Gazoo" Geithner (b. 1961) is politician and economist and from 2009 until 2013 the Secretary of the Treasury under President Obama. He attended Dartmouth College and the Johns Hopkins School of Advanced International Studies and served in the International Monetary Fund as well as the New York Federal Reserve Bank. Geithner played a key role in dealing with the financial crisis of the Great Recession and fell under the inevitable criticism of some conservatives as well as many liberals. Apparently Geithner had not paid $35,000 in taxes for the years 2001–2004. He later paid them, plus $15,000 in interest.
