Larry Summers
One of America’s leading economists, Larry Summers was a Harvard professor aged 28. He went on to be Clinton’s Secretary to the Treasury, chief economist at the World Bank, President at Harvard, and Obama’s first director of the White House National Economic Council from Jan 2009 to Nov 2010, just after the financial crisis. He has been recognised as one of the world’s most influential thinkers by Time, Foreign Policy, Prospect and The Economist magazines. Still a professor at Harvard, he writes each month for the Financial Times.
