Tatiana Schlossberg, Environmental Journalist and Granddaughter of John F. Kennedy, Dies at 35

By The Global Herald Staff January 3, 2026

Tatiana Celia Kennedy Schlossberg, the accomplished environmental journalist, author, and granddaughter of President John F. Kennedy, died on December 30, 2025, at the age of 35. Her family announced her passing in a poignant statement shared via the John F. Kennedy Presidential Library Foundation’s Instagram account: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.” The statement was signed by her husband George Moran, her children Edwin and Josephine Moran, her parents Edwin and Caroline Kennedy, and her siblings Jack, Rose, and Rory.

Schlossberg’s death came just over a month after she publicly revealed her battle with acute myeloid leukemia (AML), a rare and aggressive blood cancer, in a deeply personal essay published in The New Yorker on November 22, 2025—the 62nd anniversary of her grandfather’s assassination. Diagnosed in May 2024 shortly after giving birth to her daughter, Schlossberg underwent intensive treatments, including chemotherapy, two stem cell transplants, and participation in clinical trials. Despite these efforts, the cancer, complicated by a rare genetic mutation known as Inversion 3, proved terminal.

Born on May 5, 1990, in New York City, Tatiana was the middle child of Caroline Kennedy, the only surviving child of President John F. Kennedy and Jacqueline Kennedy Onassis, and designer Edwin Schlossberg. Raised in Manhattan, she attended elite schools including Brearley and Trinity before graduating from Yale University in 2012 with a degree in history. She later earned a master’s in American history from the University of Oxford.

Schlossberg carved her own path in journalism, focusing on climate change and environmental issues. She worked as a reporter for The New York Times‘ Science section, covering the hidden impacts of everyday consumption on the planet. Her contributions extended to The Atlantic, The Washington Post, Vanity Fair, and Bloomberg News. In 2019, she published her acclaimed book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, which explored how seemingly innocuous choices—like streaming videos or fast fashion—contribute to climate change.

Inconspicuous Consumption Author Discusses Climate Change

The book, praised by the Society of Environmental Journalists for providing “a route to feeling empowered with possibilities for positive change,” reflected Schlossberg’s passion for making complex issues accessible. She had been planning a follow-up book on oceans before her diagnosis derailed those ambitions. In recent years, she freelanced and maintained a newsletter, News from a Changing Planet.

In 2017, Schlossberg married George Moran, a physician she met at Yale, in a private ceremony at Jacqueline Kennedy Onassis’s former estate on Martha’s Vineyard. The couple welcomed a son, Edwin, around 2022, and a daughter in May 2024. Tragically, her cancer was discovered hours after the birth, when routine bloodwork revealed abnormally high white blood cell counts.

In her New Yorker essay, titled “A Battle With My Blood,” Schlossberg wrote candidly about the physical and emotional toll of her illness. She described grueling chemotherapy sessions, a near-fatal postpartum hemorrhage, and the heartbreak of facing a terminal prognosis while raising young children. “Maybe my brain is replaying my life now because I have a terminal diagnosis, and all these memories will be lost,” she reflected. Her older sister, Rose, donated stem cells for one transplant, underscoring the family’s close bond.

Schlossberg also addressed broader implications, expressing concern over policies under Health and Human Services Secretary Robert F. Kennedy Jr., her mother’s cousin. As a vaccine skeptic who oversaw cuts to medical research funding, including for mRNA technologies potentially useful against cancers, she worried about access to vaccines while immunocompromised. “As I spent more and more of my life under the care of doctors, nurses, and researchers… I watched as Bobby cut nearly a half billion dollars for research into mRNA vaccines,” she wrote.

The Kennedy family has endured profound losses across generations, from the assassinations of President Kennedy in 1963 and Senator Robert F. Kennedy in 1968, to the 1999 plane crash that claimed John F. Kennedy Jr. Schlossberg’s death adds another layer of sorrow, yet her courage in sharing her story drew widespread admiration.

Tributes poured in from relatives and public figures. Journalist Maria Shriver, a cousin, called her “valiant, strong, courageous” and praised her journalism for educating others on saving the planet. Presidential historian Tom Whalen evoked a quote about Robert F. Kennedy: “For such a person, the sunset should never have come before the afternoon.”

Schlossberg is survived by her husband George Moran; children Edwin and Josephine; parents Caroline Kennedy and Edwin Schlossberg; siblings Rose and Jack Schlossberg; and extended family. Her legacy endures through her writing, which urged action on climate change, and her unflinching honesty in facing adversity.

In her essay’s closing reflections, Schlossberg pondered the fragility of life and memory. Her words—and her impact—will not be forgotten.
