Zenzile Miriam Makeba nicknamed Mama Africa, was a South-African singer, civil rights activist, and human right campaigner. In the 1960s, Makeba was the first vocalist to put African music onto the international map . She’s best known for her song "Pata, Pata,” which was first recorded in 1957 and later released in the U.S. in 1967. She recorded and toured with many well-known artists, such as Harry Belafonte, Paul Simon (Graceland tour), and her former husband Hugh Masekela. Makeba campaigned against apartheid and in response, the South African government revoked her passport in 1960 and her citizenship and right of return in 1963. Once the apartheid system crumbled she returned home for the first time in 1990. Makeba died of a heart attack in 2008 after performing in a concert in Italy organized to support writer Roberto Saviano in his stand against the Camorra—a mafia-like organization. In 1966, Makeba received the Grammy Award for Best Folk Recording together with Harry Belafonte for An Evening with Belafonte/Makeba. Despite industry pressure, she wore no makeup, refused to curl or straighten her hair for shows, thus establishing a style that would come to be known internationally as the "Afro look." Her marriage to Trinidad-born civil rights activist, Black Panther, and Student Nonviolent Coordinating Committee leader Stokely Carmichael in 1968 caused controversy in the United States, and her record deals and tours were cancelled. After Nelson Mandela was released from Victor Verster Prison on February 11, 1990, he persuaded Miriam Makeba to return to South Africa. She returned home on June 10, 1990. In 2001, she was awarded the Otto Hahn Peace Medal in Gold by the United Nations Association of Germany in Berlin for “outstanding services to peace and international understanding". She continued making music and working as a civil rights activist until her death.
