Courageous Battle Against Terminal Cancer
Schlossberg revealed her terminal diagnosis in a powerful essay published by The New Yorker last month, exactly 62 years after her grandfather’s assassination. She was diagnosed with acute myeloid leukemia in May 2024, shortly after giving birth to her second child.
Despite undergoing chemotherapy, bone marrow transplants, and experimental immunotherapy treatments, the cancer returned aggressively, leading doctors to give her a one-year prognosis.
In her essay, Schlossberg expressed profound concern about adding another tragedy to her family’s already heavy burden of loss. “For my whole life, I have tried to be good, to be a good student and a good sister and a good daughter, and to protect my mother and never make her upset or angry,” she wrote with characteristic grace.
Environmental Journalist and Author Legacy
Tatiana built an impressive career as an environmental journalist and author, distinguishing herself beyond her famous family name.
Her 2020 book “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have” earned the Society of Environmental Journalists’ prestigious Rachel Carson Environment Book Award. The judging panel praised how readers would “find solace, humor and a route to feeling empowered with possibilities for positive change.”
Political Criticism in Final Essay
Schlossberg’s final public writing included pointed criticism of her cousin, Health Secretary Robert F. Kennedy Jr., regarding cuts to government medical research funding. She noted that one of her chemotherapy drugs, cytarabine, was developed from Caribbean sea sponge research conducted at UC Berkeley in 1959, likely with government funding.
“This discovery was made by scientists who almost certainly relied on government funding, the very thing that Bobby has already cut,” she wrote, highlighting concerns about reduced support for medical research.
Tatiana is survived by her husband George Moran, whom she married in 2017 at the family’s Martha’s Vineyard estate, their two young children, her parents, and siblings Rose and Jack. Her legacy as both a talented journalist and devoted mother will endure despite this latest tragedy to befall America’s most prominent political family.
