Joseph Saddler (born January 1, 1958 in Barbados) better known as Grandmaster Flash, is one of the pioneers of hip-hop deejaying, cutting, and mixing. His early influences included DJ Kool Herc and Pete Jones. 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 honored.
He became involved in the earliest New York DJ scene, attending parties set up by early luminaries. he used duplicate copies of a single record and two turntables (for cutting) but added a dexterous manual edit with a mixer to promote the break (the ordinary playing of the record would be interrupted to overlay the break, the break could be repeated by using the mixer to switch channels while the second record was spun back). He also developed the technique initially called cutting (which was developed by Grand Wizard Theodore into scratching).
