Shortly before her untimely passing at the age of 35 on December 30, 2025, environmental journalist Tatiana Schlossberg shared one final, radiant moment of joy with her loved ones in a beautiful family photo.

Captured in September 2025 on Martha’s Vineyard, the image shows Tatiana sitting peacefully on the grass, smiling warmly at the camera. Beside her is her husband, George Moran, gazing lovingly in her direction, while their two young children—son Edwin (around 3 years old) and daughter Josephine (just over a year old)—complete the tender scene. The casual, sunlit setting, with the family dressed simply and relaxed, captures pure, unfiltered happiness amid unimaginable hardship.

This poignant photograph, later shared by the JFK Library Foundation in her memory, stands as a powerful reminder of Tatiana’s enduring spirit. As the granddaughter of former U.S. President John F. Kennedy and daughter of Caroline Kennedy and Edwin Schlossberg, Tatiana was known for her work as an acclaimed environmental journalist, including her time at The New York Times and her 2019 book Inconspicuous Consumption.

Her battle began shortly after giving birth to her daughter in May 2024, when routine tests revealed an abnormally high white blood cell count. The diagnosis: acute myeloid leukemia (AML) with a rare mutation (Inversion 3), an aggressive form of blood and bone marrow cancer typically seen in older patients. In a raw, courageous essay published in The New Yorker on November 22, 2025—titled “A Battle With My Blood”—Tatiana openly shared her journey through intensive chemotherapy, a postpartum hemorrhage that nearly took her life, multiple stem cell transplants (including one from her sister Rose), and experimental treatments. Doctors ultimately told her she had less than a year to live, describing the condition as terminal.

Despite the grueling treatments and the profound fear of leaving her young family, Tatiana faced everything with remarkable grace, infinite love, and unwavering honesty. She wrote movingly about cherishing every moment with her husband and children, reflecting on memories, and even critiquing policies that impacted medical research and care during her illness.

That final family photo, released after her death, radiates the same light she carried through her struggle—a testament to a brave woman who lived fully, loved deeply, and left an indelible mark on her family, her field, and the world. Tatiana Schlossberg will forever live in the hearts of those she touched, a symbol of resilience, joy, and quiet strength. Her legacy endures in her words, her advocacy for the environment, and the unbreakable love she shared with her family.
