Schlossberg was a climate change and environmental journalist and the second child of JFK's daughter, former US diplomat Caroline Kennedy, and the designer-artist Edwin Schlossberg.

In a New Yorker essay published in November, Schlossberg said she had been diagnosed with acute myeloid leukemia with a rare mutation, a cancer of the blood and bone marrow.

At the time, she also criticized her cousin Robert F. Kennedy Jr., the US health secretary, for being a vaccine skeptic and cutting funding for cancer research.
