Here’s a clear, up-to-date summary of the breaking news about Tatiana Schlossberg, based on multiple trusted news reports:

Tatiana Schlossberg, granddaughter of President John F. Kennedy, has died at age 35. Her family announced her passing on December 30, 2025 via a statement shared by the John F. Kennedy Presidential Library and Museum.

She was an environmental journalist and author, known for her work on climate and environmental issues, including reporting for The New York Times and other major outlets and a critically acclaimed book on hidden environmental impacts.

Schlossberg publicly revealed in November 2025, in an essay for The New Yorker, that she had been diagnosed with acute myeloid leukemia in May 2024, shortly after the birth of her second child. Her illness involved a rare mutation that made it particularly aggressive and difficult to treat.

She underwent extensive treatment—including chemotherapy, a bone marrow transplant, and clinical trials—but the disease eventually proved fatal.

Tatiana is survived by her husband, Dr. George Moran, their two young children, her parents Caroline Kennedy and Edwin Schlossberg, and her siblings Rose and Jack Schlossberg.

In her final public writings, she reflected on life, illness, and the urgent need to address climate and health care issues, even calling attention to the impact of public health policy on research funding.

Her passing is widely mourned as a profound loss—both personally for her family and professionally for the journalism and environmental communities.
