Brave Battle Against Terminal Cancer Diagnosis
Schlossberg revealed her terminal cancer diagnosis in a deeply personal essay published by The New Yorker last month, exactly 62 years after her grandfather’s assassination. She underwent extensive treatment including chemotherapy, bone marrow transplants, and experimental immunotherapy trials. Despite the aggressive treatment regimen, the cancer returned, and doctors gave her approximately one year to live.
Environmental Legacy and Professional Accomplishments
Schlossberg built a distinguished career as an environmental journalist and author, earning the Society of Environmental Journalists’ Rachel Carson Environment Book Award in 2020 for “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have.”
The award recognized her ability to help readers find empowerment and positive change through environmental awareness. She had planned to write a second book about ocean conservation before her diagnosis derailed those ambitions.
Political Commentary in Final Public Writing
In her final essay, Schlossberg took aim at her cousin Robert F. Kennedy Jr., now serving as Health Secretary under President Trump. She criticized his cuts to government research funding, noting that one of her chemotherapy drugs originated from government-funded research at UC Berkeley in 1959.
This criticism reflects ongoing tensions within the Kennedy family over political positions and government spending priorities that resonate with many Americans concerned about fiscal responsibility.
Family Focus During Final Months
Schlossberg spent her remaining time focused on her young family, including her husband George Moran, whom she married in 2017 at the family’s Martha’s Vineyard estate. The couple had two children: a son born in 2022 and a daughter born in May 2024, just before Schlossberg’s cancer diagnosis.
Her essay poignantly described the challenge of being present with her children while grappling with her mortality, writing about watching herself and her kids grow up simultaneously through childhood memories.
