Margaret Morganroth Gullette is one of the nation’s leading voices on the negative impacts and violence of ageism. Gullette, 81 and a resident scholar at the Women’s Studies Research Center of Brandeis University, is the author of “Ending Ageism, or How Not to Shoot Old People” (Rutgers University Press, 2017), which won the MLA Prize for Independent Scholars and the Society for the Psychology of Women’s Florence L. Denmark Award for Contributions to Women and Aging. One of her oft-repeated refrains is “Fear ageism, not aging,” and she is working on her next book, “American Eldercide.”
