Martha Lillard, the last known American polio patient to use an iron lung, died at age 78 in Oklahoma. Her death marks the end of a significant chapter in the history of polio treatment in the United States, where the iron lung was once a common life-support device for patients with severe respiratory paralysis caused by the disease.
Lillard’s death was confirmed by her family and local health authorities in Oklahoma. She had been reliant on the iron lung since contracting polio in childhood, during the height of the polio epidemic in the 1950s. Her condition made her the last known individual in the U.S. to depend on this mechanical ventilator for breathing support.
Medical records and family statements indicate that Lillard lived a relatively active life despite her condition, participating in community activities and advocating for polio awareness. Her reliance on the iron lung was a symbol of the era before widespread vaccination and advanced respiratory treatments.
Her death is being noted as a historical milestone, representing the final chapter of a period when iron lungs were used in the United States, which largely phased out after the development of the polio vaccine and modern ventilators in the 1960s and 1970s.
Historical Significance of Martha Lillard’s Passing
Lillard’s death underscores the success of vaccination campaigns that eradicated polio in the U.S. and the decline of life-support devices like the iron lung. Her passing symbolizes the closing of a chapter in medical history, illustrating how far disease prevention and treatment have advanced.
This milestone also highlights ongoing global efforts to eliminate polio and the importance of vaccination programs, especially as polio remains endemic in some parts of the world.

Polio and Iron Lung Use in the 20th Century
During the 1950s, polio was a major public health crisis in the United States, with thousands affected annually. The iron lung, a large mechanical respirator, became a common treatment for patients with paralysis of the respiratory muscles.
Following the development of the Salk vaccine in 1955, cases of polio declined sharply. The widespread adoption of the vaccine in the 1960s led to the near elimination of the disease in the U.S. and the phasing out of iron lungs. Martha Lillard’s reliance on the device made her a living reminder of that era.
Her death at age 78 in Oklahoma marks the last known case of an American dependent on this device, a milestone acknowledged by health historians and medical experts.
“Martha Lillard’s passing is a poignant reminder of how far we’ve come in disease prevention and treatment.”
