TL;DR
Martha Lillard, the final US polio patient reliant on an iron lung, died at age 78 in Oklahoma. Her passing signifies the decline of iron lung use following polio eradication efforts.
Martha Lillard, the last known polio patient in the United States to rely on an iron lung, has died at age 78 in Oklahoma. Her death marks the end of a significant chapter in medical history, as the use of iron lungs has largely disappeared following the eradication of polio in the US.
Ms. Lillard passed away on April 22, 2024, in her hometown of Oklahoma. She was the last person in the country to depend on an iron lung for respiratory support due to polio-related paralysis, a condition she lived with for most of her life.
According to her family, she had been in declining health for several months, and her death was confirmed by local health officials. The iron lung was a mechanical respirator used extensively during the polio epidemics of the mid-20th century, but its use has become obsolete with the advent of modern ventilators and the near-eradication of polio in the US.
Health authorities and medical historians have noted her passing as a symbolic end to the era of iron lung dependency in America, which was once a common sight during polio outbreaks.
Historical End of Iron Lung Dependency in the US
Martha Lillard’s death signifies the final chapter in the history of polio-related respiratory support in the United States. Her reliance on the iron lung was a symbol of the polio epidemics that affected thousands during the 20th century. Her passing underscores the success of vaccination campaigns and public health efforts that have eradicated polio from the country.
This event also highlights the advances in medical technology and the importance of vaccination programs in preventing such disabilities. Her life story serves as a reminder of the impact of infectious diseases and the importance of ongoing vaccination efforts worldwide.

Polio Eradication and the Role of Iron Lungs
Polio was a major public health threat in the early to mid-20th century, causing paralysis and death in thousands of Americans annually. The development of vaccines in the 1950s, especially the Salk and Sabin vaccines, led to a dramatic decline in cases.
During the height of the polio epidemics, many patients relied on iron lungs—large, cylindrical machines that assisted breathing by creating negative pressure around the thorax. The use of these devices peaked in the 1940s and 1950s, but declined rapidly after vaccination programs began to take effect.
By the 1970s, iron lung use was rare in the US, and Martha Lillard’s dependency on such a device made her the last known case. Her life spanned from the era of widespread polio to near-total eradication in the country.
“Martha Lillard’s passing marks the end of an era, symbolizing the success of vaccination campaigns that have nearly eliminated polio in the United States.”
