In the final months of her courageous battle with acute myeloid leukemia, Tatiana Schlossberg quietly made a profound decision that speaks volumes about her character: She donated $1 million to The Leukemia & Lymphoma Society (LLS), the world’s largest nonprofit dedicated to funding research, providing free education, and offering support to patients with blood cancers. The gift, confirmed by sources close to the family and LLS, was made in complete silence—no press release, no public announcement, no fanfare—reflecting Tatiana’s lifelong commitment to meaningful action over spotlight.

The donation, executed privately just weeks before her death on December 30, 2025, at age 35, will support LLS’s mission: accelerating breakthrough research into treatments for leukemia, lymphoma, myeloma, and other blood cancers; funding patient assistance programs; and providing critical information and emotional support to families facing diagnosis. “Tatiana wanted to help others fighting the same battle she faced,” a source familiar with the gift shared. “She believed in the power of science, compassion, and hope—and she chose to contribute without drawing attention to herself.”

Tatiana, the granddaughter of President John F. Kennedy, daughter of Caroline Kennedy and Edwin Schlossberg, and a respected environmental journalist, had already shared her diagnosis publicly in a raw November 2025 New Yorker essay. There, she described the shock of learning about her rare mutation while recovering from childbirth, the grueling treatments—including chemotherapy, two bone marrow transplants (one from sister Rose), and clinical trials—and her deep love for husband George Moran and children Edwin (3) and Josephine (19 months). Yet she kept this final act of generosity private, consistent with her approach to life: impactful work done without seeking praise.

The Leukemia & Lymphoma Society, which has invested over $1.5 billion in research since 1949, praised the anonymous gift upon confirmation: “This generous contribution will fuel lifesaving research and support for patients who need it most. Tatiana’s quiet compassion will continue to save lives long after she’s gone.”

Friends and family say the donation was deeply personal. “She knew firsthand the fear of a diagnosis, the hope in new trials, the importance of support,” one close friend said. “Tatiana didn’t want recognition—she wanted progress.”

In her New Yorker essay, Tatiana expressed gratitude for medical advances that gave her time with her family and urged continued funding for research—values mirrored in this final gift. Her mother Caroline Kennedy, who supported her through every treatment, has long advocated for health issues; this donation aligns with the family’s tradition of service, quietly extended by Tatiana.

As tributes continue pouring in—Maria Shriver calling her “valiant, strong, courageous”—this $1 million act stands as a silent testament: Even in her final days, Tatiana chose to lift others.

She didn’t seek headlines.
She sought hope—for those still fighting.
Tatiana Schlossberg: A life of quiet impact.
A gift of $1 million in silence.
A legacy of love—enduring.
Rest in peace, Tatiana.
Your light continues to heal.
