Peter Kavanagh was just an infant when he was diagnosed with paralytic polio and suffered permanent paralysis in the lower part of his left leg. As a child, Kavanagh endured painful medical procedures to even out the length of his legs, and experimental exercise techniques. He spent his youth in a leg brace and special footwear, isolating for a boy whose classmates ran freely in sneakers. His first lesson in walking was how to move while wearing such equipment. Throughout his life, as he developed a very successful career in public broadcasting, built a family, and indulged in his love of music and travel, Kavanagh underwent various surgeries and rehabilitation to give him "normal" mobility.
