NEW YORK -- Anne Cox Chambers, heiress to a fortune made in part from newspapers, has died, two years after suffering a stroke. She was 100.

Chambers died Wednesday of natural causes at her home in Greenwich, Connecticut, according to her spokeswoman. She was nearly 8 months shy of her 101st birthday.

Chambers, the seventh child of the late media tycoon William Randolph Hearst, was born in Virginia. She later moved to Greenwich and is a U.S. citizen.

She helped found the New York Free Press newspaper, named for Hearst's Wall Street bureaus. She also held a majority stake in Hearst Corp., the media company that controlled the New York Times and other newspapers.

She also founded an aggressive lobbying organization that sought changes in the editorial policies of newspapers, including the eventual creation of a nationwide news media ownership cap and the mandate for public broadcasting.

After Hearst died in 1942, she spent the next 35 years maintaining control of her fortune.

Chambers married Leonard Chambers, a lawyer and civil rights activist, in 1960 and he died in 2004. He died less than three months after the birth of their son, media heir Justin Chambers.
