Happy National Hispanic Heritage Month! How much do you know about these important Latino Americans?

Hispanic Heritage Month celebrates the "histories, cultures and contributions of American citizens whose ancestors came from Spain, Mexico, the Caribbean and Central and South America," according to the official website. It lasts from September 15 to October 15, a time period that includes independence day celebrations in many Latin American countries. (What's the difference between Hispanic and Latino? Hispanic refers to those who come from Spanish-speaking countries; Latino refers to those whose ancestors come from Latin America.)
