Douglas "Jocko" Henderson (March 8, 1918 – July 15, 2000) was an American radio disc jockey, businessman, and hip hop music pioneer.
[4][5] He was known for a distinctive style of rhythmic patter in his radio voice, which he had learned from a Baltimore deejay, Maurice "Hot Rod" Hulbert.
[3] In the 1950s and early 1960s it was common practice for record companies to lavish gifts on disc jockeys in exchange for airplay of their songs.
Scepter also gave him publishing rights to songs such as "Baby It's You" and "Will You Love Me Tomorrow", which he eventually sold to avoid suffering the same fate as Freed.
[9] In 1978, Henderson made an unsuccessful bid for a seat in the United States House of Representatives in Pennsylvania's 2nd congressional district.
