Conservative activist Phyllis Schlafly, best known for being the voice of opposition to the Equal Rights Amendment, died on Monday. She was 92.
Her death was confirmed by her son John, who said she died of cancer at her home in St. Louis.
According to The Associated Press, Schlafly's self-published book, A Choice Not an Echo, brought her into the national spotlight in 1964. The news service reports the book, which sold 3 million copies, became a manifesto for many conservatives and boosted Sen. Barry Goldwater's bid for the 1964 GOP presidential nomination.
