Gloria Steinem, the celebrated author and activist who became one of the most visible symbols and potent voices of the U.S. women's movement and a fierce advocate for feminist causes throughout her life, has died.

With her trademark streaked hair parted down the middle and large aviator glasses, Steinem, a co-founder of Ms. Magazine, was a hugely recognizable presence wherever she went.

And she went everywhere: Much of her life as an advocate was spent on the road, speaking at college campuses and community centers, at rallies and marches.
