Martha Lillard, the last person in the United States to rely on an iron lung for breathing, passed away, making the end of a chapter in American medical history that goes back to the devastating polio epidemics of the 20th century. Martha Lillard’s Demise According to her kin, Martha Lillard, 78, died on June 26, 2026, at her home in Shawnee, Oklahoma. She had spent close to 73 years living with the effects of paralytic polio, a disease that permanently damaged the muscles needed for breathing, leaving her dependent on an iron lung, a medical device that has now become obsolete. According to reports, chronic pulmonary failure and post-polio syndrome were listed among the causes of her death. Her family also said she experienced long COVID, which further worsened her lung function, increasing the amount of time she needed to spend inside the iron lung.Also read: Donald Trump Says Physical Checkup At Walter Reed 'Checked Out Perfectly' Amid Recent Health Scrutiny Martha Lillard’s Post-Polio Syndrome Lillard contracted polio in 1953 when she was just five years old, during one of the worst outbreaks in U.S. history. Before effective vaccines became available, the virus infected tens of thousands of Americans each year. While many people recovered, some developed paralytic polio, in which the virus attacks the nervous system, leading to paralysis and, in extreme cases, respiratory failure. Doctors placed Lillard inside an iron lung, a large cylindrical machine that uses negative air pressure to help patients breathe by expanding and contracting the chest. Although hospitals gradually replaced iron lungs with ventilators in the 1960s, Lillard continued using the ancient device because it proved to be the most effective method of respiratory support for her. Her family said maintaining the iron lung became increasingly challenging as replacement parts and technicians familiar with the obsolete technology became hard to find. Still, Lillard continued using the machine well into her seventies. Martha Lillard Refused To Let It Define Her Despite spending most of her life inside the machine, Lillard refused to let it define her. According to her family members and previous interviews, she attended school from home through an intercom system connected to her classroom. She also became fond of painting, writing poetry, composing music, and caring for rescued animals. She also volunteered with community organizations, including the Humane Society. Lillard's passing comes more than 70 years after Jonas Salk's polio vaccine was introduced in 1955, followed by Albert Sabin's oral vaccine in the early 1960s. Widespread immunisation campaigns in the US significantly polio cases. The epidemic was eliminated from the country in 1979. As one of the last survivors to depend on an iron lung, Martha Lillard's life serves as a reminder of both the devastating impact of vaccine-preventable diseases and the extraordinary developments made in public health.
