WASHINGTON, DC - OCTOBER 09:  Janet Yellen smiles as U.S. President Barack Obama (L) and current Chairman of the Federal Reserve Ben Bernake (R) applaude her during a press conference to nominate Yellen to head the Federal Reserve in the State Dining Room at the White House on October 9, 2013 in Washington, DC. If confirmed Yellen would be the first woman to lead the worlds most powerful central bank, replacing Ben Bernanke. Yellen was appointed vice chair in October 2010. She was president and CEO of the Federal Reserve Bank of San Francisco from 2004 to 2010 and also served as chair of the Council of Economic Advisors from 1997 to 1999.
