William Graham, a member of the family that owned The Washington Post for decades, died at his home of a self-inflicted gunshot wound, his brother said.

Donald Graham, a former publisher and chief executive of the Post, told the newspaper that his brother passed away on Dec. 20 in Los Angeles. William Graham was 69.

William Graham worked as a lawyer in Washington before moving to Los Angeles, where he taught trial law, according to the Post.

Parents Philip and Katharine Graham both served as leaders of the Post. Katharine Graham was publisher when the newspaper's coverage of Watergate helped bring down President Richard Nixon in the 1970s.

Philip Graham died after shooting himself at his farm in Virginia in August 1963 after being released from a psychiatric hospital where he had been for six weeks. His death at age 48 was ruled a suicide.

The eldest Graham had been at the helm of the Post since 1946, and also bought Newsweek magazine in 1961, according to his New York Times obituary.

His son William was 14 at the time of his death, and Katharine took over the paper in 1963. She died from head injuries she suffered after falling on a sidewalk in Sun Valley, Idaho, in 2001. She was 84.

William Graham's death came days before the release of the movie "The Post," which chronicled the newspaper's fight with the government over the release of the Pentagon Papers. Oscar-winner Meryl Streep plays Katharine Graham in the movie.

His grandfather, Eugene Meyer, bought the paper in 1933, and it stayed within the family for 80 years.

Graham was active in the anti-war movement during the Vietnam era and would graduate from the University of California, Los Angeles law school after attending Stanford, according to the Post. He would later spend 20 years operating an investment company that he founded, according to the newspaper.
