Antoine Dominique "Fats" Domino Jr. (February 26, 1928 – October 24, 2017) was an American pianist and singer-songwriter of Louisiana Creole descent. One of the pioneers of rock and roll music, Domino sold more than 65 million records. Between 1955 and 1960, he had eleven Top 10 hits. His humility and shyness may be one reason his contribution to the genre has been overlooked.
During his career, Domino had 35 records in the U.S. Billboard Top 40, and five of his pre-1955 records sold more than a million copies, being certified gold. His musical style was based on traditional rhythm and blues, accompanied by saxophones, bass, piano, electric guitar, and drums.
His 1949 release "The Fat Man" is widely regarded as the first million-selling Rock 'n Roll record. SOURCE: Wikipedia
