Tatiana Schlossberg, JFK’s Granddaughter and Environmental Journalist, Passes Away at 35 After Brave Battle

By ClickUSA News Staff | December 31, 2025

In a heartbreaking end to 2025, Tatiana Schlossberg — the talented environmental journalist, author, and granddaughter of President John F. Kennedy — has passed away at the age of 35. The Kennedy family announced her death on December 30, sharing a poignant statement: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.”

Tatiana, the middle child of Caroline Kennedy (JFK’s only surviving daughter) and designer Edwin Schlossberg, leaves behind a legacy of intellect, passion for the planet, and unwavering courage in the face of adversity. Just over a month ago, in a raw and moving essay for The New Yorker titled “A Battle With My Blood,” she revealed her diagnosis of acute myeloid leukemia (AML) with a rare mutation known as Inversion 3 — a terminal form of the aggressive blood cancer that struck shortly after the birth of her second child in May 2024.

A Life Cut Tragically Short: From Kennedy Heir to Climate Advocate

Born Tatiana Celia Kennedy Schlossberg on May 5, 1990, in New York City, she grew up in the shadow of one of America’s most iconic families — granddaughter to JFK and Jackie Kennedy Onassis, niece to John F. Kennedy Jr., and cousin to figures like Maria Shriver and Robert F. Kennedy Jr. Yet Tatiana chose a path far from the political spotlight, carving out her own identity as a sharp-minded journalist dedicated to environmental issues.

A Yale University graduate (Class of 2012) with a master’s from Oxford, Tatiana worked as a climate reporter for The New York Times, contributing to outlets like The Atlantic, The Washington Post, and Bloomberg. Her 2019 book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, earned acclaim for exposing the hidden climate costs of everyday life — from fashion to food.

Married to physician George Moran since 2017 (in a quiet ceremony at the Kennedy compound in Martha’s Vineyard), Tatiana was a devoted mother to two young children: a son and a daughter named Josephine. In her final essay, she heartbreakingly wrote about her fear that her kids might not remember her, while cherishing the “wonderful life” she built with her family.

Her siblings — older sister Rose Schlossberg (a filmmaker and comedian) and younger brother Jack Schlossberg (currently running for Congress in New York) — stood by her side. Rose even donated stem cells for Tatiana’s transplant, a desperate bid to beat the disease.

The Courageous Fight Against Acute Myeloid Leukemia

Tatiana’s battle began unexpectedly postpartum, when routine bloodwork revealed abnormalities. What followed was relentless: chemotherapy, a near-fatal hemorrhage, stem cell transplants, clinical trials, and relapses. Despite the grim prognosis — doctors estimated she had perhaps a year left — Tatiana faced it with grace, honesty, and even humor in her writing.

Cousin Maria Shriver paid tribute, calling her “valiant, strong, courageous” and praising her work to “educate others about the earth and how to save it.” The Kennedy family, no strangers to tragedy, has once again been touched by profound loss.

What Are Acute Myeloid Leukemia Symptoms?

Acute myeloid leukemia (AML) is a fast-progressing cancer of the blood and bone marrow. Common symptoms include:

• Fatigue and weakness
• Frequent infections
• Easy bruising or bleeding
• Shortness of breath
• Fever
• Bone pain
• Pale skin

Tatiana’s case, with its rare mutation, highlighted how AML can strike young, healthy people unexpectedly.

As the world mourns this bright light from the Kennedy lineage — often called the “Kennedy curse” in whispers — Tatiana Schlossberg’s words and work endure. She reminded us all to live fully, fight fiercely, and protect the planet for future generations.

Rest in peace, Tatiana. The Kennedy family, and the world, will miss you.
