Joseph Saddler (born January 1, 1958 in Bridgetown, Barbados), better known as Grandmaster Flash, is an American hip hop recording artist and DJ—one of the pioneers of hip-hop DJing, cutting, and mixing.
He has been credited with the invention of the first crossfader by sourcing parts from a junkyard in the Bronx.[by whom?] It was initially an On/Off toggle switch from an old microphone that he transformed into a left/right switch which allowed him to switch from one turntable to another, thereby avoiding a break in the music.
Grandmaster Flash and the Furious Five were inducted into the Rock and Roll Hall of Fame in 2007, becoming the first hip hop/rap artists to be so honored.
