She made her way to the museum’s second-floor library, where she joined Anna Danziger Halperin, the director of the Historical’s Center for Women’s History. Aidem, who has the eclectic style of a woman who knows her way around a craft fair (paisley blouse, shaggy Mongolian-lamb coat, a tangle of beaded necklaces), was led to a table covered with women’s-lib ephemera. “Second-wave-feminist history is my main academic focus,” Halperin said. “So a lot of these things I already had sitting around my office.” Aidem loved a set of “working women” paper dolls from 1974, which included a postal employee, a doctor, and a construction worker. Her eyes lit on a 1978 issue of Working Mother magazine, with the cover line “Time for Yourself: How to Save, Buy It, and Make It (Without Feeling Guilty).”journey-inline-newsletterinline-newsletter
