Robert Strange McNamara was an American business executive and the eighth United States Secretary of Defense, serving from 1961 to 1968 under Presidents John F. Kennedy and Lyndon B. Johnson. He played a major role in escalating the United States' involvement in the Vietnam War. McNamara was responsible for the institution of systems analysis in public policy, which developed into the discipline known today as policy analysis.
He was born in San Francisco, California, graduated from UC Berkeley and Harvard Business School and served in the United States Army Air Forces during World War II. After the war, Henry Ford II hired McNamara and a group of other Army Air Force veterans to work for Ford Motor Company. These "Whiz Kids" helped reform Ford with modern planning, organization, and management control systems. After briefly serving as Ford's president, McNamara accepted appointment as Secretary of Defense.
McNamara became a close adviser to Kennedy and advocated the use of a blockade during the Cuban Missile Crisis. Kennedy and McNamara instituted a Cold War defense strategy of flexible response, which anticipated the need for military responses short of massive retaliation.
