The writer and environmental activist announced her cancer diagnosis just one month before her passing.

Following a courageous battle with cancer, :contentReference[oaicite:0]{index=0} passed away at the age of 35 on Tuesday, December 30. Her death marked a profound loss not only for her family, but also for the world of journalism and environmental advocacy.

Tatiana was the daughter of :contentReference[oaicite:1]{index=1} and :contentReference[oaicite:2]{index=2}, and the granddaughter of :contentReference[oaicite:3]{index=3}. Despite carrying one of the most recognized family names in American history, she built a thoughtful and independent career defined by intellect, integrity, and purpose.

A respected journalist, Tatiana worked as a writer for :contentReference[oaicite:4]{index=4} and contributed frequently to major publications including :contentReference[oaicite:5]{index=5}, :contentReference[oaicite:6]{index=6}, :contentReference[oaicite:7]{index=7}, and :contentReference[oaicite:8]{index=8}. In 2019, she published her debut book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, which examined how everyday habits quietly contribute to climate change.

News of her passing was shared by the :contentReference[oaicite:9]{index=9}, which released a statement reading, “Our beautiful Tatiana passed away this morning. She will always be in our hearts.”

The message was signed by her husband, George Moran; her children, Edwin and Josephine; her parents, Edwin Schlossberg and Caroline Kennedy; her siblings, Jack and Rose; and her cousin, Rory.

In November, Tatiana revealed her diagnosis in a deeply personal essay titled “A Battle with My Blood”, published in :contentReference[oaicite:10]{index=10}. In the piece, she shared that she had been diagnosed with acute myeloid leukemia, a rare and aggressive form of cancer.

She explained that the diagnosis came in May 2024, shortly after giving birth to her second child, Josephine. Tatiana noted that the disease is typically found in older patients, and that doctors had asked whether she had spent significant time at Ground Zero following the September 11 attacks.

“I was in New York on 9/11 in the sixth grade,” she wrote. “I didn’t visit the site until years later.”

As she confronted the reality of her illness, Tatiana reflected on the challenge of staying present with her young children, writing that while presence is often encouraged, “being in the present is harder than it sounds.”

She also wrote movingly about her son, Edwin, explaining her desire to be remembered not only through illness, but through purpose. “My son knows that I’m a writer and that I write about our planet,” she shared. “Since I’ve been sick, I remind him a lot, so that he will know I was not just a sick person.”

Tatiana Schlossberg leaves behind a legacy of thoughtful journalism, environmental awareness, and deeply human storytelling. Her words continue to resonate as a reminder of the impact one voice can have—both on the page and in the lives of those left behind.
