Daniel Ellsberg, a military analyst and researcher whose 1971 Pentagon Papers leak led to him being dubbed “the most dangerous man in America”, has passed away at his home in Kensington, California, his family said. He was 92.

In a statement late Friday, his family said he died due to pancreatic cancer. “Daniel was a seeker of truth and a patriotic truth-teller, an anti-war activist, a beloved husband, father, grandfather, and great-grandfather, a dear friend to many, and an inspiration to countless more. He will be dearly missed by all of us,” the statement read.
