Los Angeles (CNN) — Don Cornelius, the founder of the “Soul Train” television show, was found dead of an apparent self-inflicted gunshot wound to his head Wednesday, authorities said. He was 75.

Cornelius died of a gunshot wound at a house on Mulholland Drive, said Los Angeles police Officer Tenesha Dodine. Police responded to the call about 4 a.m. (7 a.m. ET), Dodine said.

Cornelius was pronounced dead at Cedars-Sinai Medical Center, according to Lt. Larry Dietz of the Los Angeles County Coroner’s Office.

Los Angeles police investigators reported to the coroner that Cornelius died from a “self-inflicted gunshot wound to the head,” coroner’s Assistant Chief Ed Winter said. The coroner’s office will perform an autopsy to confirm the cause of death.

Cornelius created a pilot for “Soul Train” using $400 of his own money, according to the website biography.com. The show was named after a promotional event he put together in 1969, the site said.

Gladys Knight, who performed on the pilot of the show more than four decades ago, said Cornelius “opened up so many avenues for African-American artists.”

In an interview with CNN Wednesday, Knight said he appeared in ill health when she saw him recently.

“Last time I saw him, he was pretty sick,” Knight said. “He had lost a lot of weight, but he still had that thing about him.”

Singer Aretha Franklin called his death “so sad, stunning and downright shocking.”

“Don Cornelius single-handedly brought about a melding and unity of brother and sisterhood among young adults worldwide and globally with the unforgettable creation of ‘Soul Train,'” Franklin said.
