Donald Henry “Don” Rumsfeld (born July 9, 1932) is a retired American political figure and businessman. Rumsfeld served as Secretary of Defense from 1975 to 1977 under Gerald Ford, and again from 2001 to 2006 under George W. Bush. He is both the youngest and the second-oldest person to have served as Secretary of Defense. Additionally, Rumsfeld was a three-term U.S. Congressman from Illinois (1963–1969), Director of the Office of Economic Opportunity (1969–1970), Counsellor to the President (1969–1973), the United States Permanent Representative to NATO (1973–1974), and White House Chief of Staff (1974–1975).
Born in Illinois, Rumsfeld attended Princeton University, graduating in 1954 with a degree in political science. After serving in the Navy for three years, he mounted a campaign for Congress in Illinois’ 13th Congressional District, winning in 1962 at the age of 30. While in Congress, he was a leading co-sponsor of the Freedom of Information Act. Rumsfeld reluctantly accepted an appointment by President Richard Nixon to head the Office of Economic Opportunity in 1969; appointed Counsellor by Nixon and entitled to Cabinet-level status, he would also head up the Economic Stabilization Program before being appointed Ambassador to NATO. Called back to Washington in August 1974, Rumsfeld was appointed Chief of Staff by President Ford. Rumsfeld recruited a young one-time staffer of his, Dick Cheney, to succeed him when Ford nominated him to be Secretary of Defense in 1975.
When Ford lost the 1976 election, Rumsfeld returned to private business life, and was named president and CEO of the pharmaceutical corporation G. D. Searle & Company. He was later named CEO of General Instrument from 1990 to 1993, and chairman of Gilead Sciences from 1997 to 2001.
Rumsfeld was appointed Secretary of Defense for a second time in January 2001 by President George W. Bush. During his tenure he aimed to modernize and restructure the U.S. military for the 21st century. Rumsfeld played a central role in the planning of the United States’ response to the September 11 attacks, which included two wars, one in Afghanistan and one in Iraq. In addition to war strategy, Rumsfeld’s tenure became highly controversial for the use of enhanced interrogation techniques as well as the Abu Ghraib torture and prisoner abuse scandal. Rumsfeld gradually lost political support and he resigned in late 2006.
Rumsfeld was known in media circles for his outspokenness and candor. In his retirement years, he published an autobiography Known and Unknown: A Memoir as well as Rumsfeld’s Rules: Leadership Lessons in Business, Politics, War, and Life. He is involved with the Rumsfeld Foundation’s Fellowship program, which has advisors at dozens of universities across the United States, and supports several military-related causes.
