Fortune's writeup from 1998: The yank running this venerable British media conglomerate--home to the Financial Times, The Economist, Penguin Putnam books, and TV's Baywatch--is making some brash moves: She's buying Simon & Schuster's educational publishing unit, which will make Pearson the world's largest in that field. Combined revenues total $5.3 billion; about 60% of that comes from the U.S.
*Scardino is the only International MPW on this allstar list, as her first appearance was on Fortune's domestic Most Powerful Women in Business list.
