Harold George "Harry" Belafonte, Jr. (born March 1, 1927) is an American singer, songwriter, actor and social activist. He was dubbed the "King of Calypso" for popularizing the Caribbean musical style with an international audience in the 1950s. Belafonte is perhaps best known for singing "The Banana Boat Song", with its signature lyric "Day-O". Throughout his career he has been an advocate for civil rights and humanitarian causes and was a vocal critic of the policies of the George W. Bush Administration.

Born Harold George Bellanfanti, Jr., at Lying-in Hospital, Harlem, New York, Belafonte was the son of Melvine (née Love) – a housekeeper of Jamaican descent – and Harold George Bellanfanti, Sr., a Martiniquan who worked as a chef in the National Guard. From 1932 to 1940, he lived with his grandmother in her native country of Jamaica. When he returned to New York City, he attended George Washington High School after which he joined the Navy and served during World War II. In the 1940s, he was working as a janitor's assistant in NYC when a tenant gave him, as a gratuity, two tickets to see the American Negro Theater. He fell in love with the art form and also met Sidney Poitier. The financially struggling pair regularly purchased a single seat to local plays, trading places in between acts, after informing the other about the progression of the play. At the end of the 1940s, he took classes in acting at the Dramatic Workshop of The New School in New York with the influential German director Erwin Piscator alongside Marlon Brando, Tony Curtis, Walter Matthau, Bea Arthur and Sidney Poitier, while performing with the American Negro Theatre. He subsequently received a Tony Award for his participation in the Broadway revue John Murray Anderson's Almanac.
