Officers on the scene told TMZ that Cornelius' body was discovered around 4 a.m. PST, and that they believe Cornelius committed suicide. He was taken to a nearby hospital where he was pronounced dead.
As creator and host of the "Hippest Trip in America," Cornelius is credited with bringing African-American music to the national forefront with "Soul Train," which ran from 1970 to 2007 and would become the longest-running first-run nationally syndicated show in TV history, according to the Los Angeles Times.
Most recently, Cornelius told the LA Times about developing a movie about "Soul Train." "It wouldn't be the 'Soul Train' dance show, it would be more of a biographical look at the project," he said.
Don Cornelius was 75.
