Daniel Ellsberg worked on the top-secret McNamara study, 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. Ellsberg’s subsequent trial on twelve felony counts, posing a possible sentence of 115 years, was dismissed in 1973 on grounds of governmental misconduct against him, leading to the convictions of several White House aides and figuring in the impeachment proceedings against President Nixon.

Since the end of the Vietnam War, Ellsberg has been a lecturer, scholar, writer and activist on the dangers of the nuclear era, wrongful U.S. interventions and the urgent need for patriotic whistleblowing.
