Robert Gates

Gates was nominated by Republican president George W. Bush as secretary of defense in 2006, replacing Donald Rumsfeld. He was confirmed with bipartisan support. In 2007, ''Time'' named Gates one of the year's most influential people. In 2008, Gates was named one of America's Best Leaders by ''U.S. News & World Report''. He continued to serve as secretary of defense in President Barack Obama's administration and retired in 2011. "He'll be remembered for making us aware of the danger of over-reliance on military intervention as an instrument of American foreign policy," said former senator David L. Boren. Gates was presented the Presidential Medal of Freedom, the nation's highest civilian award, by President Obama during his retirement ceremony.
Since leaving the Obama administration, Gates was elected president of the Boy Scouts of America, served as Chancellor of the College of William & Mary, and served as a member on several corporate boards. In 2012, Gates was elected as a fellow of the National Academy of Public Administration. Provided by Wikipedia
