Martha Lillard, the last known polio patient in the United States to use an iron lung, has died at age 78 in Oklahoma. Her death marks the end of an era in the history of polio treatment and reflects the success of vaccination efforts that made such devices obsolete.
Ms. Lillard passed away on March 23, 2024, in her hometown of Oklahoma. She was diagnosed with polio as a child in the 1950s, during the height of the disease’s prevalence in the US, and relied on an iron lung for respiratory support for several decades.
The iron lung, a mechanical respirator that encases the body to assist breathing, was a common treatment for severe polio cases before the advent of vaccines. Ms. Lillard’s use of the device became a symbol of the polio epidemic and the challenges faced by patients during that period.
According to her family, she was a resilient individual who lived a full life despite her health challenges. Her death is confirmed by local health officials and her family members, who stated she passed peacefully at her home.

Polio and the Evolution of Respiratory Care in the US
Polio was a major public health threat in the US during the first half of the 20th century, with thousands of cases annually before vaccines were introduced. The development of the Salk and Sabin vaccines in the 1950s led to a dramatic decline in cases. The iron lung, introduced in the 1920s, was a critical device for those with paralysis of respiratory muscles, with many patients relying on it for years or decades.
By the late 20th century, widespread vaccination and improved medical care rendered the iron lung largely obsolete. Martha Lillard’s reliance on the device made her a symbol of the era prior to these advances, and her death underscores how far public health has come.
“Martha Lillard’s passing marks the end of a chapter in medical history. Her resilience and the progress in polio prevention are a testament to the importance of vaccination programs.”
