Helen Gurley Brown (b. 1922) is a bestselling writer and editor considered one of the most influential figures of Second Wave feminism. Editor-in-chief at Cosmopolitan for thirty-two years, Brown transformed the magazine from a staid, behind-the-times women's publication to one of most widely read magazines among young women in the United States. Brown's trailblazing book Sex and the Single Girl jump-started the sexual revolution when it was published in 1962. Her fun, flirty, and unabashed advice helped a generation of women navigate the changing cultural norms both inside and outside the bedroom, and inspired the follow-up book Sex and the Office (1965). Brown lives in New York City.
