A private funeral service for Tatiana Schlossberg was held on January 5, 2026, at the Church of St. Ignatius of Loyola on Manhattan’s Upper East Side — the same church where her grandmother, Jacqueline Kennedy Onassis, had her memorial service in 1994. The atmosphere was solemn and respectful, with family, friends, and close associates gathering to honor her memory in a dignified ceremony.

Tatiana, who died on December 30, 2025, at age 35 after a courageous battle with acute myeloid leukemia, was deeply mourned by her immediate family. In attendance were her parents, Caroline Kennedy and Edwin Schlossberg, and her siblings Jack and Rose Schlossberg. Her husband, George Moran, brought their two young children, Edwin and Josephine, highlighting both her roles as a devoted professional and a loving mother.

The service drew a broad group of public figures and family friends, underscoring Tatiana’s wide influence. President Joe Biden, former House Speaker Nancy Pelosi, former Secretary of State John Kerry, former New York City Mayor Michael Bloomberg, designer Carolina Herrera, and television host David Letterman were among those photographed at the funeral. This mix of political, cultural, and social figures reflected her impact beyond journalism and her family’s prominence.

Tatiana Schlossberg was an accomplished environmental journalist and author, known for her climate reporting and thoughtful engagement with pressing ecological issues. A graduate of Yale University and the University of Oxford, she worked for major outlets including The New York Times and wrote the 2019 book Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have. Her reporting blended scientific clarity with a commitment to public understanding of climate and environmental challenges.

In November 2025, Tatiana publicly disclosed her terminal diagnosis in an essay for The New Yorker, sharing her struggle with leukemia and the emotional and physical impact it had on her and her family. The announcement drew widespread attention and empathy, reinforcing her reputation for courage, honesty, and introspection. Highlights included her reflections on motherhood, illness, and the connections between personal experience and public discourse.

In the aftermath of her passing, her family and the broader community have honored Tatiana as a figure of compassion, intellect, and strength. Her brother Jack Schlossberg paid tribute through social media with quotes from her work and reflections that tied her legacy to values of environmental stewardship and compassion. Family tributes emphasized her enduring influence as a writer, advocate, and cherished daughter, sister, and mother
