Daniel Ellsberg, a former military analyst and anti-war activist whose disclosure of the so-called Pentagon Papers revealed systemic US government deception about the Vietnam War, has died, his family announced in a statement. He was 92.

The cause was pancreatic cancer, his family said. Ellsberg announced his diagnosis in March, saying at the time that doctors had given him three to six months to live and that he had decided not to undergo chemotherapy.

He died on Friday at his home in Kensington, California, according to his family.

"Daniel was a seeker of truth and a patriotic truth-teller, an antiwar activist, a beloved husband, father, grandfather, and great-grandfather, a dear friend to many, and an inspiration to countless more," his family said. "He will be dearly missed by all of us."
