What disease crippled President Franklin D. Roosevelt and led him to help the nation find a cure?

The disease that crippled President Franklin D. Roosevelt and led him to help the nation find a cure was polio. Polio, short for poliomyelitis, is a highly contagious viral infection that primarily affects the nervous system, leading to paralysis and muscle weakness. In 1921, at the age of 39, Roosevelt contracted polio and was left permanently paralyzed from the waist down. This personal experience motivated him to establish the National Foundation for Infantile Paralysis, now known as the March of Dimes, to fund research for the prevention and treatment of polio.
