Franklin D. Roosevelt [SEP] Introduction
He won election to the New York State Senate in 1910, and then served as Assistant Secretary of the Navy under President Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's 1920 national ticket, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness, believed at the time to be polio, and his legs became permanently paralyzed. While attempting to recover from his condition, Roosevelt founded a rehabilitation center in Warm Springs, Georgia, for people with poliomyelitis. In spite of being unable to walk unaided, Roosevelt returned to public office by winning election as Governor of New York in 1928.
