Not too long ago — when the poster child for “family” was displayed on “Father Knows Best,” “Leave It to Beaver” and “The Dick Van Dyke Show” — a woman raising a child without a husband was not widely accepted. In fact, some people — perhaps, at one time, even you — frowned upon such women. Since then, be it from forward-thinking Gloria Steinem, “That Girl” or “Murphy Brown,” we’ve grown to realize that women are more than capable of single-handedly running a household. Women can have complete lives (careers, children, fun) without a spouse. Today, we do not have to wait to find Mr. Right to start a family. Or, if Mr. Right turns out to be Mr. Wrong and the marriage ends, a woman can be the sole wearer of the pants. From Diane Keaton and Sandra Bullock to Toni Morrison and Linda Ronstadt, here are 18 well-known women who helped to re-define our image of “nuclear” family and shaped single motherhood into the fabulous role that it is today.
