Daniel Ellsberg was born in Chicago in 1931. After graduating from Harvard in 1952 with a B.A. summa cum laude in Economics, he studied for a year at King’s College, Cambridge University, on a Woodrow Wilson Fellowship. Between 1954 and 1957, Ellsberg spent three years in the U.S. Marine Corps, serving as rifle platoon leader, operations officer, and rifle company commander.
From 1957-59 he was a Junior Fellow in the Society of Fellows, Harvard University. He earned his Ph.D. in Economics at Harvard in 1962 with his thesis, Risk, Ambiguity and Decision. His research leading up to this dissertation—in particular his work on what has become known as the “Ellsberg Paradox,” first published in an article entitled Risk, Ambiguity and the Savage Axioms—is widely considered a landmark in decision theory and behavioral economics.
On return to the RAND Corporation in 1967, Ellsberg worked on the top secret McNamara study of U.S. Decision-making in Vietnam, 1945-68, which later came to be known as the Pentagon Papers. In 1969, he photocopied the 7,000 page study and gave it to the Senate Foreign Relations Committee; in 1971 he gave it to the New York Times, the Washington Post and 17 other newspapers. His trial, on twelve felony counts posing a possible sentence of 115 years, was dismissed in 1973 on grounds of governmental misconduct against him, which led to the convictions of several White House aides and figured in the impeachment proceedings against President Nixon.
