In 1960, doctors diagnosed Eleanor Roosevelt with aplastic anemia. The rare and, at the time, untreatable condition meant her bone marrow wasn't producing enough red blood cells. But Roosevelt, known as the "First Lady of the World," was determined to keep up with her work. She continued traveling the world until 1962, when she was too sick to continue. Wracked with fevers and a hacking cough, she went in and out of the hospital. Her doctors treated her anemia with a steroid and, suspecting she may also have tuberculosis, two different antibiotics. Upon her death on November 7, 1962, their autopsy report showed some surprising findings, which continued to arise decades later, when medical historian B.H. Lerner published his review of the case in 2000. To hear how the mystery unfolded, listen to the latest episode of The Weirdest Thing I Learned This Week.
