John Peel (1939-2004), one of the original DJs of UK's Radio 1 in 1967, known for the extraordinary range of his taste in music, and for championing unknown musical artists.
DJKool Herc (born 1955), inventor of breakbeat technique, "the godfather of hip hop culture".
The DJ has been at the center of music history for the last forty years-from the first time a record was played over the airwaves, through reggae and Northern Soul, the births of disco, hip hop, house, and techno, to the current global underground.
In 1967, DJKool Herc moved from his native Jamaica to New York, and while he adjusted his musical selection to better fit the New York party crowd, he stayed true to the sound system philosophy, bringing recorded music to open air venues, playing a loud bass and talkin' over the records.
Kool DJ Herc, the godfather of hip-hop, was born in Jamaica in 1955.
