Stephanie Coontz (born August 31, 1944) is an author, historian, and faculty member at Evergreen State College. She teaches history and family studies and is Director of Research and Public Education for the Council on Contemporary Families, which she chaired from 2001-2004. Coontz has authored and co-edited several books about the history of the family and marriage.
Coontz earned a B.A. from the American History Honors Program (1966) at the University of California, Berkeley, where she was a member of the campus political party SLATE and participated in the civil rights movement and the Free Speech Movement. Attending the University of Washington on a Woodrow Wilson Fellowship, she earned a Master of Arts in European History (1970). Abandoning further graduate work, she joined the staff of the National Peace Action Coalition, later becoming a National Coordinator; they focused on building peaceful, legal demonstrations against the Vietnam War. Before returning to full-time teaching in 1975, Coontz also had a leadership role in the Young Socialist Alliance, a Trotskyist youth group of the Socialist Workers Party (SWP). By the late 1970s, however, Coontz had parted company with the SWP.
