Martha Lillard had just turned 5 when she was diagnosed with polio and depended on an iron lung to live. She died June 26 in Oklahoma, the last U.S. polio patient who used the machine, her sister said. She was 78. “They told her she wasn’t supposed to live past 20 years old,” Lillard’s younger sister, Cindy McVey, told The Associated Press on Friday. “She had the enthusiasm and the drive to continue living and make the best of her life.”

McVey attributes her sister’s death to the effects of long Covid. A death certificate lists causes as chronic pulmonary failure and post-polio syndrome, McVey said.

Lillard slept in the iron lung cylinder that encased her body as the air pressure in the chamber forced air in and out of her lungs. As a child, she went to grade school for two hours a day and was tutored the rest of the time. She attended Shawnee High School by using a phone system that allowed her to interact with her teachers and classmates through an intercom in her classrooms.

Her family went on road trips to Missouri thanks to a custom trailer and her father calling hotels to find out if they had doors wide enough to accommodate the machine Lillard slept in. Lillard was even able to drive for a time. “To me, it was just normal,” recalled McVey, 75.
