An American former military officer and public official. He served as Director of the Central Intelligence Agency from September 6, 2011, until his resignation on November 9, 2012. Prior to his assuming the directorship of the CIA, Petraeus was a four-star general serving over 37 years in the United States Army. His last assignments in the Army were as commander of the International Security Assistance Force (ISAF) and Commander, U.S. Forces Afghanistan (USFOR-A) from July 4, 2010, to July 18, 2011. His other four-star assignments include serving as the 10th Commander, U.S. Central Command (USCENTCOM) from October 13, 2008, to June 30, 2010, and as Commanding General, Multi-National Force - Iraq (MNF-I) from February 10, 2007, to September 16, 2008. As commander of MNF-I, Petraeus oversaw all coalition forces in Iraq.

Petraeus has a B.S. degree from the United States Military Academy, from which he graduated in 1974 as a distinguished cadet (top 5% of his class). He was the General George C. Marshall Award winner as the top graduate of the U.S. Army Command and General Staff College class of 1983. He subsequently earned an M.P.A. in 1985 and a Ph.D. degree in International Relations in 1987 from the Woodrow Wilson School of Public and International Affairs at Princeton University. He later served as Assistant Professor of International Relations at the United States Military Academy and also completed a fellowship at Georgetown University.

Petraeus has repeatedly stated that he has no plans to run for elected political office. On June 23, 2010, President Barack Obama nominated Petraeus to succeed General Stanley McChrystal as commanding general of the International Security Assistance Force in Afghanistan, technically a step down from his position as Commander of United States Central Command, which oversees the military efforts in Afghanistan, Pakistan, Central Asia, the Arabian Peninsula, and Egypt.

On June 30, 2011, Petraeus was unanimously confirmed as the next Director of the CIA by the U.S. Senate 94-0. Petraeus relinquished command of U.S. and NATO forces in Afghanistan on July 18, 2011 and retired from the U.S. Army on August 31, 2011. On November 9, 2012, General Petraeus resigned from his position as Director of the CIA, citing an extramarital affair that was purportedly discovered in the course of an FBI investigation.
