It can't be easy sharing the screen with a Marilyn Monroe-esque sexpot and an elegant Grace Kelly lookalike. But somehow, actress Elisabeth Moss brings depth and charm to Mad Men's unlikely heroine, Peggy Olson.

Peggy's journey from passive secretary to respected copywriter isn't picture perfect. She fights the prejudices of her chauvinistic male coworkers, struggling to prove that she and her ideas are worth taking seriously. Her relationships with her conservative Catholic mother and sister are tumultuous and difficult to say the least. And then there's that pesky little pregnancy she denies up until the baby pops out and she checks into a psychiatric ward.

Moving up the corporate ladder is challenging enough today. But for a young woman in the male-dominated advertising industry in the 1960s, it seemed all but impossible. Peggy might be a fictional character, but her resolute dedication to her job and increasingly fearless quest for workplace equality is inspiring. As she becomes more confident her creative abilities, her jeering, threatened male coworkers are forced to accept her as an equal, valued member of Sterling Draper Cooper Price.
