"When she stopped conforming to the conventional picture of femininity she finally began to enjoy being a woman. " - Betty Friedan
She's a sad loss, but she had SUCH a full life where she accomplished so much. So much, for instance, of the early work Betty did, the crtitiques she made, are now unquestionably obvious facts to so many, when that wasn't at all so before her work.
Friedan was one of the oiginal founders (and the first president) of NOW, a big activist in the (continuing) struggle to get the ERA introduced and passed. The Feminine Mystique is STILL an incredible piece of work, and sparked the second wave of the feminist movement.
Really anyone with an interest in/passion for women's equality, feminism, and just the visibility of women and their lives -- or who now enjoys the privildge of any aspect of those things -- overall owes Friedan a pretty huge debt.
