Sept. 4, 1947: Earl Griffin gives some hard shots to disc jockey Al Jarvis of KLAC-AM (570, in case you’re Atwater Kent is working). Jarvis was credited with using black artists on his radio show as early as 1933, but the L.A. Sentinel columnist says Jarvis “has hoodwinked the public into believing he was the ‘great white father’ of our group.”

Griffin goes on to critique an ad on Jarvis’ “Make Believe Ballroom” for a housing development that didn’t say the homes were restricted to whites. He also criticizes a listeners’ contest for records made by members of Local 47 of the musicians union without saying that black musicians were barred from Local 47.

Jarvis, dubbed “the dean of disc jockeys” by the Los Angeles Times, died of a heart attack in 1970 at the age of 60 after a long career in radio and early television.
