The statement that Eva Peron was also known as the Cinderella of Argentina is true. Eva Peron was the first lady of Argentina from 1946 until her death in 1952 (she was the wife of the President Juan Perón).
Tomás Eloy Martínez referred to Eva Perón as "The Cinderella of the tango and the Sleeping Beauty of Latin America." in an interview in 1996.
