Most of what you think you know about Rosa Parks may well be wrong. On the verge of the 100th anniversary of her birth this Monday comes a fascinating new book, "The Rebellious Life of Mrs. Rosa Parks," by Jeanne Theoharis, a Brooklyn College professor. It argues that the romanticized, children's-book story of a meek seamstress with aching feet who just happened into history in a moment of uncalculated resistance is pure mythology. As Theoharis points out, "Rosa's family sought to teach her a controlled anger, a survival strategy that balanced compliance with militancy."
