Tatiana Schlossberg, granddaughter of President John F. Kennedy, has disclosed she’s battling aggressive leukemia with doctors estimating she has less than twelve months remaining—a devastating prognosis she revealed Saturday on the 62nd anniversary of her grandfather’s assassination.
The 35-year-old climate journalist and mother of two shared her diagnosis in a New Yorker essay titled “A Battle With My Blood,” describing how acute myeloid leukemia upended her life after childbirth in May 2024. Despite bone marrow transplants and chemotherapy, physicians have delivered grim assessments about her survival prospects.
“During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe,” Schlossberg wrote. “My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me.”
Her son was born in 2022, her daughter in 2024—children who may grow up with only photographs and stories of their mother, much as Schlossberg herself barely remembers her grandmother Jacqueline Kennedy Onassis, who died of cancer when Tatiana was a toddler.
Schlossberg is the daughter of designer Edwin Schlossberg and diplomat Caroline Kennedy, who previously served as U.S. ambassador to Australia and Japan. The essay reveals her anguish over the pain her death will inflict on her mother, who has already endured extraordinary family tragedy.
“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. “Now I have added a new tragedy to her life, to our family’s life, and there’s nothing I can do to stop it.”

The Kennedy family’s history reads like a catalog of premature deaths and shattered promise. Tatiana’s uncle John F. Kennedy Jr. died in a plane crash at 38. Her grandfather President Kennedy was assassinated at 46. Great-uncle Robert F. Kennedy was murdered while running for president. The pattern of loss has made the family synonymous with both political achievement and personal catastrophe.
Schlossberg described herself as previously healthy, an active runner and skier who once swam New York’s Hudson River “eerily, to raise money for the Leukemia and Lymphoma Society”—a fundraiser that now carries tragic irony given her diagnosis.
Her essay also addresses watching second cousin Robert F. Kennedy Jr. become Trump’s health secretary while she fought for survival in hospital. “I watched from my hospital bed as Bobby, in the face of logic and common sense, was confirmed for the position, despite never having worked in medicine, public health, or the government,” she wrote. “Suddenly, the healthcare system on which I relied felt strained, shaky.”
Schlossberg has been an outspoken critic of RFK Jr.’s anti-vaccine positions and his appointment to oversee American health policy—criticism that carries added weight now that her own life depends on medical science her cousin has often questioned.
Her brother Jack Schlossberg announced this month he’s planning a congressional run in New York. He shared Tatiana’s essay Saturday with the caption: “Life is short – let it rip.”
The Kennedy family’s generations-spanning role in American politics, combined with the personal tragedies that have repeatedly struck its members, has secured it a unique place in national consciousness—a dynasty defined equally by public service and private grief.
For Tatiana Schlossberg, the family’s legacy of loss now includes her own terminal diagnosis, revealed on the anniversary of the assassination that defined the Kennedys’ place in American memory and set in motion decades of tragedy that continues claiming the family’s youngest generation.
