Francis Warren Nicholls Jr., known professionally as Frankie Knuckles, was an American DJ, record producer, and remixer. He played an important role in developing and popularizing house music, a genre of music that began in Chicago during the early 1980s and subsequently spread worldwide. In 1997, Knuckles won the Grammy Award for Remixer of the Year, Non-Classical. Due to his importance in the development of the genre, Knuckles was often called "The Godfather of House Music".

House is a genre of electronic dance music characterized by a repetitive four-on-the-floor beat and a typical tempo of 120-130 beats per minute as a re-emergence of 1970s disco. It originated in the Black queer community in Chicago. It was created by DJs and music producers from Chicago's underground club culture and evolved slowly in the early/mid 1980s as DJs began altering disco songs to give them a more mechanical beat. By early 1988, House became mainstream and supplanted the typical 80s music beat.
