ST. LOUIS (AP) -- Phyllis Schlafly, the outspoken conservative activist who helped defeat the Equal Rights Amendment in the 1970s and founded the Eagle Forum political group, has died. She was 92.

Schlafly's family was with her when she died Monday afternoon of cancer at her home in St. Louis, her son John Schlafly said. Funeral arrangements are pending, he said.

Schlafly rose to national attention in 1964 with her self-published book, "A Choice Not an Echo," that became a manifesto for the far right. The book, which sold three million copies, chronicled the history of the Republican National Convention and is credited for helping conservative Sen. Barry Goldwater of Arizona earn the 1964 GOP nomination.
