Phyllis McAlpin Schlafly was an American constitutional lawyer, movement conservative, and conservative activist. She held staunchly conservative social and political views, supported antifeminism, opposed abortion, and successfully campaigned against ratification of the Equal Rights Amendment to the U.S. Constitution. Her book, A Choice Not an Echo (1964), a polemic against Republican leader Nelson Rockefeller, sold more than three million copies. Schlafly co-authored books on national defense and was critical of arms control agreements with the Soviet Union. In 1972, Schlafly founded the Eagle Forum, a conservative political interest group, and remained its chairwoman and CEO until her death in 2016.
