Little is more fabulous than the modernist worlds of prewar and interwar Paris, and American women were there in droves, present in salons and nightclubs. The National Portrait Gallery’s newest exhibition celebrates the lives of 60 globe-trotting women, all of whom made a dent in the scene. The show includes portraits of Josephine Baker, Gertrude Stein, Peggy Guggenheim, Edna St. Vincent Millay, Zelda Fitzgerald, and many more. They may not have called themselves feminists, but in their liberty these women embodied 20th-century authority and agency, and ushered in a brave new world. —Lucy Horowitz
