A Prominent Environmental Voice
Tatiana Celia Kennedy Schlossberg was born on May 5, 1990, in New York City. She was the middle child of Caroline Kennedy, a diplomat and author, and artist Edwin Schlossberg. She carried on a legacy of public service and intellectual curiosity. Schlossberg pursued higher education at prestigious institutions. She earned a bachelor's degree in history from Yale University in 2012. Later, she completed a master's degree in American history from the University of Oxford in 2014.[en+3]
Schlossberg built a notable career as an environmental journalist. She worked as a science and climate reporter for The New York Times. Her writing also appeared in major publications like The Atlantic, The Washington Post, Vanity Fair, and Bloomberg News. In 2019, she authored the book "Inconspicuous Consumption: The Environmental Impact You Don't Know You Have." This work highlighted the often-overlooked environmental consequences of everyday actions. The book received critical acclaim, winning first place in the Society of Environmental Journalists' Rachel Carson Environment Book Award in 2020.[en+3]
Her journalism focused on humanizing complex environmental issues. Colleagues regarded her as a meticulous and hardworking reporter. She often immersed herself in nature and consulted with scientists for her stories. Schlossberg also contributed to the annual Profile in Courage Award at the John F. Kennedy Presidential Library and Museum. She frequently accompanied her mother during diplomatic engagements as ambassador to Japan and Australia.[en+1]
A Fierce Fight Against Leukemia
Schlossberg's health battle began unexpectedly in May 2024. She was diagnosed with acute myeloid leukemia (AML) at age 34. This diagnosis came shortly after she gave birth to her second child. Doctors noted an unusually high white blood cell count. Further tests revealed a rare mutation called Inversion 3, which often indicates a more aggressive form of the disease.[en+8]
In November 2025, Schlossberg publicly shared her terminal diagnosis in a poignant essay. The piece, titled "A Battle With My Blood," was published in The New Yorker magazine. She described the shock of her diagnosis, recalling that she had felt healthy and active, even swimming a mile while nine months pregnant. "This could not possibly be my life," she wrote, reflecting on the abrupt nature of AML.[oncodaily+7]
Her essay detailed the grueling 18 months of treatment she endured. This included multiple rounds of chemotherapy and two bone marrow transplants. Her sister, Rose Schlossberg, was one of the stem cell donors. Schlossberg also participated in a clinical trial for a new type of immunotherapy. Despite these intensive efforts, the cancer continued to progress. Her doctors informed her that her prognosis was terminal, giving her less than a year to live.[oncodaily+3]
Family's Grief and Public Commentary
Tatiana Schlossberg was married to Dr. George Moran, a urologist, whom she wed in 2017. The couple had two young children: a son, Edwin, born in 2022, and a daughter, Josephine, born in 2024. Her essay in The New Yorker candidly expressed her deep anguish about leaving her young family. She wrote about her fears that her children might grow up without memories of her. Schlossberg also shared her sadness about not being able to continue her "wonderful life" with her husband.[en+7]
In her powerful essay, Schlossberg also voiced criticism of her cousin, Robert F. Kennedy Jr. At the time, he served as the Health and Human Services Secretary. She argued that policies he supported, particularly his skepticism toward government-funded medical research and vaccines, could negatively impact cancer patients. Schlossberg called his actions "an embarrassment" in her essay. This piece was published on November 22, the 62nd anniversary of her grandfather's assassination.[hindustantimes+3]
Her passing brought an outpouring of tributes. Maria Shriver, a niece of John F. Kennedy, remembered Schlossberg as "the light, the humor, the joy" and a great journalist. Shriver noted that Schlossberg "used her words to educate others about the earth and how to save it." She added that Tatiana loved her life and "fought like hell to try to save it."[ctvnews]
