"It's better to be a lion for a day than a sheep all your life."

Elizabeth Kenny (20 September 1880 – 30 November 1952) was an unaccredited Australian nurse who promoted a controversial new approach to the treatment of poliomyelitis. Her findings ran counter to conventional medical wisdom; they demonstrated the need to exercise muscles affected by polio instead of immobilising them. Kenny's principles of muscle rehabilitation became the foundation of physical therapy, or physiotherapy.
