Martha Ann Lillard, 78, who survived polio and depended for decades on a 1940s-era iron lung to breathe, dies on June 26, according to reporting from multiple outlets. Lillard is described as the last known U.S. polio survivor living in an iron lung. She spent more than 70 years using the mechanical ventilator after her polio illness left her unable to breathe independently. One account states that her death followed a breakdown of the aging machine that maintained her breathing and that it could not be repaired due to the device’s age. Other coverage emphasizes her long reliance on the historic device and her status as a final living representative of that specific medical circumstance for polio survivors in the United States. Together, the reports highlight her decades-long use of the 1940s breathing machine and her death at a time when iron lung patients are exceptionally rare, underscoring a shift from polio-related respiratory disability toward prevention and modern care.
