Tatiana Schlossberg Biography

Tatiana Celia Kennedy Schlossberg was born on May 5, 1990, in New York City to diplomat Caroline Kennedy and designer Edwin Arthur Schlossberg, making her the granddaughter of President John F. Kennedy and Jacqueline Kennedy Onassis. She graduated from Yale University with a BA in history, where she served as editor-in-chief of the Yale Herald, and later earned a Master's degree in American History at the University of Oxford. Schlossberg began her journalism career as a general reporter and quickly found her niche covering science and climate topics at The New York Times, where her work earned her recognition for clear, impactful writing on environmental issues. She authored the Rachel Carson Environmental Book Award-winning book Inconspicuous Consumption: The Environmental Impact You Don Know You Have, which examined the hidden environmental costs of everyday consumer choices. Her freelance work appeared in The Washington Post, The Atlantic, Vanity Fair, The Boston Globe, Bloomberg, and Yale Environment 360, and she maintained her own climate newsletter as a dedicated freelancer.

Terminal Cancer Diagnosis and Public Essay

In May 2024, on the very day she gave birth to her second child, Schlossberg's doctor detected an abnormality in her white blood cell count that led to her diagnosis of acute myeloid leukemia with a rare mutation called Inversion 3. Despite undergoing extensive treatment including chemotherapy, bone marrow transplants, and a clinical trial for CAR-T-cell immunotherapy against blood cancers, doctors told her she had less than a year to live. On November 22, 2025, the 62nd anniversary of her grandfather JFK's death, she publicly revealed her diagnosis in a moving essay titled A Battle With My Blood published in The New Yorker, which was later printed in the magazine's December 8 issue under the title A Further Shore. Her candid essay drew worldwide sympathy and admiration for her bravery, and she took direct aim at her cousin Robert F. Kennedy Jr., the US Secretary of Health and Human Services under President Trump, criticizing his skepticism toward vaccines and reduction of cancer research funding.
