And even though Anna Wintour's name might not be as instantly recognizable as Oprah Winfrey's or Martha Stewart's, Anna, American Vogue's editor-in-chief, might still be influencing unsuspecting consumers about what they wear, how they shop and what celebrity or cause is about to be the talk of the town.

That's why WSJ, the glossy lifestyle magazine published by The Wall Street Journal, is featuring her on its cover with an article exploring her power and influence in the fashion industry beyond the pages of her magazine.

"She's a really powerful figure in America ... someone whose power extends beyond what she does," says Deborah Needleman, editor of WSJ, which scored the rare profile of Wintour — and posed cover photograph — for its April issue.

Despite her image as an ice queen, those who know her say she can be loyal and even warm to those in her inner circle, which reads like a Who's Who list: Karl Lagerfeld, Marc Jacobs, Oscar de la Renta, Harvey Weinstein, Mayor Michael Bloomberg, Nicole Kidman, Roger Federer and Amar'e Stoudemire, among them.
