Dana Anderson
Senior VP-Marketing, Strategy and Communication, Kraft Foods
As an agency exec, Dana Anderson was known to keep a brass bra in her office as a sign that she was just as tough as the boys. After blazing trails as president of DDB and FCB in Chicago, becoming one of the first women in the city to rise to that level, she joined Kraft in 2009, where she has pursued cutting-edge creative while remaking the food giant's agency roster at an almost breakneck pace.On Oct.1 she will move to Mondelez International, the new home for Kraft's global snack brands. These days her message to fellow marketers is to toss aside conventional thinking to take what she calls "leaps."

Susan Arnold
Former President, Procter & Gamble Co.
Procter & Gamble Co. has marketed to women for well over a century, but until Susan Arnold came along, women had never played a big role in the uppermost reaches of senior management.In 1999, she became the company's first female president, overseeing a skin-care business that was building Olay into a $2 billion-plus global powerhouse. She led much of the transformation early this century into one of the biggest beauty players in the world.
Ultimately, Ms. Arnold would become P&G's first vice chair, then rise to head all of the company's global business units in 2007 before retiring in 2009, denting -- but not breaking -- the glass ceiling to the CEO office.
