Early Career

Daniel Ellsberg joined the RAND Corporation in 1958 as a strategic analyst specializing in nuclear strategy and command and control of nuclear weapons.

In 1962, he obtained his Ph.D. in economics from Harvard, focusing his dissertation on decision theory, which later became known as the Ellsberg paradox.

This paradox challenged the notion that decisions made under uncertain circumstances could align with subjective probabilities, significantly impacting subsequent research.

Involvement in The Vietnam War

In 1964, Ellsberg began working at the Pentagon under Secretary of Defense Robert McNamara. Following this, he spent two years in South Vietnam as a member of the State Department, working alongside General Edward Lansdale.

Upon his return to the United States, Ellsberg resumed his position at RAND. In 1967, he contributed to a classified study on the Vietnam War, referred to as the “Pentagon Papers.”

Questioning the Government and Whistleblowing

By 1969, Ellsberg’s involvement in anti-war events while still employed at RAND led him to reevaluate the government’s role in an unjust war.

Influenced by individuals like Janaki Tschannerl, a peace activist from India, and draft resister Randy Kehler, Ellsberg began to doubt the government’s actions and beliefs. This skepticism eventually motivated him to make copies of the Pentagon Papers.

Sharing the Truth with the Public

In 1970, Ellsberg worked at the Center for International Studies at the Massachusetts Institute of Technology. During this period, he shared copies of the Pentagon Papers with several newspapers, including The New York Times and The Washington Post.

The publication of these documents exposed the government’s deceptive actions and falsehoods surrounding the Vietnam War.

Legal Battles and Public Perception

The Nixon administration attempted to prevent further publication of the Pentagon Papers, resulting in legal conflicts that ultimately reached the Supreme Court.

In a landmark ruling, the court upheld the press’s right to publish, marking a significant turning point in public perception of the war and leading to a decline in trust towards the government.

Daniel Ellsberg’s Legacy

Daniel Ellsberg’s courageous actions, coupled with subsequent events like the Watergate scandal, unveiled the extent of government deceit and the erosion of trust in political leaders. His pivotal role in exposing the truth remains an indelible part of American history.


He caused a major political controversy in 1971 when he released the Pentagon Papers, which were classified documents containing a study of the U.S. government’s decision-making during the Vietnam War. The documents were given to newspapers like The New York Times and The Washington Post.

In January 1973, Ellsberg faced charges under the Espionage Act of 1917, as well as other charges of theft and conspiracy. If convicted, he could have been sentenced to a maximum of 115 years in prison.

However, due to misconduct by the government and illegal gathering of evidence, along with the defense provided by Leonard Boudin and Harvard Law School professor Charles Nesson, Judge William Matthew Byrne Jr. dismissed all charges against Ellsberg in May 1973.

Activism and Views

Daniel Ellsberg, a former military analyst, gained fame for his courageous act of leaking the Pentagon Papers in 1971. These papers were a confidential study that examined the United States’ involvement in the Vietnam War. Their publication shed light on the government’s dishonesty and manipulation surrounding the war.

Prior to this event, Ellsberg had worked as a strategic analyst at the RAND Corporation and later for the Department of Defense, granting him access to classified documents related to the conflict. Growing disenchanted with the war and alarmed by the government’s distortion of facts and objectives, Ellsberg made a momentous decision.

He chose to disclose the Pentagon Papers to the media, aiming to inform the public and shape public opinion. Several newspapers, including The New York Times, published the leaked documents, which triggered a legal battle over the government’s attempts to halt further publication.

Ellsberg faced charges under the Espionage Act for his involvement in leaking the papers. However, due to government misconduct during the trial, he managed to evade conviction. Nonetheless, his actions had a profound impact on public perception of the war, fueling mounting opposition both within the United States and abroad.

Following the Pentagon Papers incident, Ellsberg persisted in his activism and emerged as a vocal critic of U.S. government policies, particularly those related to war and nuclear weapons. He actively participated in numerous anti-war movements and championed the cause of whistleblowers. Ellsberg expressed solidarity with figures like Chelsea Manning and Edward Snowden, advocating for transparency and government accountability.

In recent years, Ellsberg has continued to address various issues, with a particular focus on the perils of nuclear weapons and the urgent need for global disarmament. Through books and interviews, he shares his invaluable insights and experiences as a whistleblower and activist.

Awards and Honors

In 1978, Ellsberg accepted the Gandhi Peace Award from Promoting Enduring Peace as a testament to his commitment to peace. Furthermore, on September 28, 2006, he received the Right Livelihood Award, acknowledging his prioritization of peace and truth, even at great personal risk, and his dedication to inspiring others to do the same.

In 2016, he was honored with the Dresden Peace Prize, and in subsequent years, he received the esteemed Olof Palme Prize in 2018 and the Sam Adams Award in 2022. These accolades recognize Ellsberg’s outstanding contributions and serve as a testament to his enduring impact on society.
