Betty Friedan (1921-2006) is hailed by historians as a seminal figure in the 'Second Wave' of the women's feminist movement. In 1957, Friedan wrote a questionnaire for her former classmates at a reunion at the all-female, Smith College. The results revealed that many women shared the same frustrations as her in their roles as housewives and mothers. Friedan's findings provided a clear-eyed analysis of the issues that affected women's lives in the decades after the Second World War, and became the basis to her book, The Feminine Mystique. A sensation on publication selling over 3 million copies, it established Friedan as one of the chief architects of the women's liberation movement.
