Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was one of the most popular American singers of the 20th century. A cultural icon, he is widely known by the single name Elvis. He is often referred to as the "King of Rock and Roll" or simply "the King".

Born in Tupelo, Mississippi, Presley moved to Memphis, Tennessee, with his family at the age of 13. He began his career there in 1954, working with Sun Records owner Sam Phillips, who wanted to bring the sound of African American music to a wider audience. Accompanied by guitarist Scotty Moore and bassist Bill Black, Presley was the most important popularizer of rockabilly, an uptempo, backbeat-driven fusion of country and rhythm and blues. RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who would manage the singer for over two decades. Presley's first RCA single, "Heartbreak Hotel", released in January 1956, was a number one hit. He became the leading figure of the newly popular sound of rock and roll with a series of network television appearances and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial. In November 1956, he made his film debut in Love Me Tender.
