Donald Rumsfeld was a prominent American businessman, politician, and public servant who served as the 13th and 21st U.S. Secretary of Defense under Presidents Gerald Ford and George W. Bush. Holding the distinction of being both the youngest and oldest person to occupy the role, he remains the only individual to serve two non-consecutive terms in the position. Beyond his defense leadership, Rumsfeld held key roles in multiple administrations, including White House Chief of Staff under Ford and U.S. Permanent Representative to NATO.
Before entering public service, Rumsfeld served as a U.S. Navy aviator from 1954 to 1957 and later transferred to the Naval Reserve. His political career included four terms in the U.S. House of Representatives, along with appointments in federal commissions and councils. In later years, he chaired the Rumsfeld Foundation, which promotes leadership, public service, and democratic economic systems worldwide. He and his wife, Joyce, raised three children and were grandparents to six grandchildren and two great-grandchildren.
