Betty Friedan’s best-seller, The Feminine Mystique, describes what she called the “problem that has no name.” By 1970, five million copies will have been sold, spurring the creation of the modern feminist movement. Based on interviews of women from Friedan’s 1942 graduating class at Smith College, the book reveals that some women, particularly those living in the suburbs, felt isolated and hopeless because their role as wives and mothers made them financially, intellectually and emotionally dependent on their husbands.
