In 1960, Harvard’s sister college, Radcliffe, announced the founding of an Institute for Independent Study, a “messy experiment” in women’s education that offered paid fellowships to those with a PhD or “the equivalent” in artistic achievement. Five of the women who received fellowships—poets Anne Sexton and Maxine Kumin, painter Barbara Swan, sculptor Marianna Pineda, and writer Tillie Olsen—quickly formed deep bonds with one another that would inspire and sustain their most ambitious work. They called themselves “the Equivalents.” Drawing from notebooks, letters, recordings, journals, poetry, and prose, Maggie Doherty weaves a moving narrative of friendship and ambition, art and activism, love and heartbreak, and shows how the institute spoke to the condition of women on the cusp of liberation.
