Final chapter for the iron lung era as polio survivor dies at 78
Martha Lillard, the last known U.S. polio patient dependent on an iron lung, died at 78 in Oklahoma; contracted polio at age five and spent most of her life in the device, yet she learned via tutoring and traveled with her family. Her death certificate cites chronic pulmonary failure and post-polio syndrome, highlighting both the disease’s history and the vaccine-era decline of polio in the U.S.
