Gloria Steinem, the feminist crusader who personified the modern women's movement for over half a century, died Wednesday at her home in New York City at age 92. Her death was announced on social media without a stated cause. Steinem helped galvanize sweeping cultural transformations across American life, from the boardroom to the courtroom. Recognizable by her tinted aviator glasses and center-parted blond hair, she co-founded Ms. magazine in 1971, the first national glossy periodical created, owned, and run entirely by women, which became the movement's manifesto.

Born a transient in the Midwest, Steinem endured a difficult childhood caring for her mentally anguished mother after her parents' divorce. Her feminist awakening arrived in her mid-30s while covering a 1969 "speak out" on illegal abortions. Charismatic and media-savvy, she led protests, founded advocacy groups, established rape crisis centers, and raised millions for women's causes. She authored nearly a dozen books, with her latest, "An Unexpected Life," slated for September publication.

Despite her public fearlessness, Steinem privately wrestled with self-esteem and a fear of public speaking, using her signature glasses and long hair as a shield. She defied stereotypes of feminists as humorless, maintaining a glittering social life and relationships with figures like director Mike Nichols and mogul Mort Zuckerman.
