March of Dimes is a United States nonprofit organization that works to improve the health of mothers and babies. The organization was founded by President Franklin D. Roosevelt in 1938, as the National Foundation for Infantile Paralysis, to combat polio. The name "March of Dimes" was coined by Eddie Cantor. After funding Jonas Salk's polio vaccine, the organization expanded its focus to the prevention of birth defects and infant mortality. In 2005, as preterm birth emerged as the leading cause of death for children worldwide, research and prevention of premature birth became the organization's primary focus.
