Helen Gurley Brown (1922–2012) was a bestselling writer and editor considered one of the most influential figures of Second Wave feminism. As editor-in-chief at Cosmopolitan for thirty-two years, starting in 1965, Brown transformed the magazine from a staid, behind-the-times women's publication to one of the most widely read magazines for young women. Brown's trailblazing book, Sex and the Single Girl, jump-started the sexual revolution when it was published in 1962. Her fun, flirty, and fearless 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 lived in New York City with her husband, David Brown, and together they became major philanthropists.
