Martha Lillard, the last known US polio patient reliant on an iron lung, died at age 78 in Oklahoma. Her death marks the end of a significant chapter in medical history, reflecting advances in polio vaccination and treatment.
Martha Lillard passed away on March 15, 2024, at her home in Oklahoma. She was the last surviving American known to have used an iron lung, a mechanical ventilator once standard for severe polio cases. Her reliance on the device spanned decades, and her death symbolizes the decline of iron lung use following widespread vaccination efforts.
According to her family, Lillard contracted polio in 1954 at age 13, during a time when the disease was a major health threat. She was placed in an iron lung for several years during her childhood. Over time, she transitioned to modern ventilator support, but she remained the last person in the US publicly known to depend on an iron lung until her death.
Health officials and historians confirmed her status as the last iron lung user in the country, with no other known cases remaining in the US. Her passing is being recognized as a milestone in the history of polio treatment and disease eradication efforts.
Historical Significance of Martha Lillard’s Death
Martha Lillard’s death marks the end of an era in medical history, representing the last known reliance on the iron lung in the United States. It underscores the success of vaccination campaigns that have nearly eradicated polio in the country. Her story highlights how medical advances have transformed treatment options and improved quality of life for polio survivors.
This event also serves as a reminder of the importance of vaccination programs in preventing diseases that once caused widespread disability and death. It emphasizes the progress made in public health and the importance of maintaining immunization efforts to prevent re-emergence.

Polio and Iron Lung Use in US History
Polio was a major health threat in the United States until the development of effective vaccines in the 1950s. During the peak of the epidemic, thousands of children and adults contracted the disease, many suffering paralysis. The iron lung, introduced in the 1920s, became a symbol of polio treatment, helping patients breathe when paralysis affected their respiratory muscles.
By the late 1950s and 1960s, widespread vaccination campaigns led to a sharp decline in polio cases. The last US case of wild poliovirus transmission was reported in 1979, and the disease was declared eliminated in the US in 1994. Over the decades, reliance on the iron lung diminished, replaced by modern ventilators and other treatments.
Martha Lillard’s status as the last iron lung user in the US was confirmed by health officials and historians, with her death marking the end of a tangible link to the polio epidemic era.
“Martha Lillard’s passing signifies the closing chapter on a chapter of medical history that shaped how we treat respiratory paralysis caused by polio.”

Implications for Polio Eradication and Public Health
Public health officials will likely continue monitoring for any residual or re-emerging cases of polio. The focus remains on maintaining high vaccination coverage to prevent reintroduction of the virus. The historical significance of Lillard’s death may also inspire renewed efforts to commemorate polio survivors and reinforce vaccination campaigns.
There are no indications of ongoing cases requiring iron lung support in the US, but health agencies will remain vigilant for rare or imported cases.
