Phyllis Schlafly was one of the most influential conservative voices of the late 20th Century. She ran for U.S. Congress in 1952 because of her interest in the communist threat and other conservative causes. She gained a reputation in Republican circles in 1964 when she self-published the treatise "A Choice, Not an Echo," which helped Barry Goldwater obtain the Republican nomination. She became interested in the Equal Rights Amendment in December 1971 and began a crusade for its defeat that was eventually successful. Schlafly continued to write, publish, and broadcast until her death in 2016.
