Courageous Battle Against Aggressive Cancer
Schlossberg received her acute myeloid leukemia diagnosis in May 2024, shortly after welcoming her second child. She endured chemotherapy, bone marrow transplants, and experimental immunotherapy trials before receiving a one-year prognosis.
Her essay revealed profound concern about adding “a new tragedy” to her family’s life, demonstrating characteristic Kennedy strength while acknowledging the burden her illness placed on loved ones who had already endured unimaginable losses.
Award-Winning Environmental Journalist’s Legacy
Schlossberg built a distinguished career as an environmental journalist and author, earning the prestigious Rachel Carson Environment Book Award in 2020 for “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have.” She planned to write about ocean conservation before cancer derailed her ambitions.
Her work focused on practical environmental solutions, offering readers “solace, humor and a route to feeling empowered with possibilities for positive change” according to award judges.
Political Commentary Amid Personal Struggle
During her treatment, Schlossberg discovered her chemotherapy drug cytarabine originated from Caribbean sea sponge research conducted at UC Berkeley in 1959 using government funding. She pointedly noted this was “the very thing that Bobby” — referring to her cousin, Health Secretary Robert F. Kennedy Jr. — “has already cut.”
This criticism highlighted concerns about reduced medical research funding affecting future cancer treatments, demonstrating her continued engagement with policy issues even while battling terminal illness.
Family Legacy Continues Through Next Generation
Schlossberg married George Moran in 2017 at the Kennedy family’s Martha’s Vineyard home after meeting at Yale University. She leaves behind two young children and focused her final months on creating memories with them.
“Mostly, I try to live and be with them now,” she wrote, describing how childhood memories merged with watching her own children grow. She is survived by her husband, children, parents Caroline Kennedy and Edwin Schlossberg, and siblings Rose and Jack.
