Schlossberg, a journalist who focused on environmental issues, bravely battled leukemia after being diagnosed last year. The John F. Kennedy Library Foundation shared news of her passing on social media Tuesday.
Maria Shriver, another niece of President Kennedy, remembered Schlossberg as a bright and joyful person who dedicated her writing to educating others about the environment. Shriver noted her courageous fight against the illness.
Schlossberg shared her experience with acute myeloid leukemia in an essay published in The New Yorker in November 2025. She described undergoing various treatments, including chemotherapy and stem cell transplants.
In her essay, Schlossberg voiced concern over health policies that could potentially harm patients battling serious illnesses, such as cancer.
Beyond her work as a reporter, Schlossberg authored “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have,” which received recognition from the Society of Environmental Journalists.
Schlossberg is survived by her husband, George Moran, and their two children. Her passing is a profound loss to her family, including her mother, Caroline Kennedy, and siblings Rose and Jack Schlossberg. The Kennedy family has faced its share of tragedy throughout the years, and this is yet another difficult moment for them.
We extend our deepest sympathies to the Schlossberg and Kennedy families during this time. Her commitment to informing the public will be remembered.
