His death was announced by Jeanette Bazzell Turner, who married Mr. Turner in 1995. She gave no cause of death, but said he had had emphysema.

Mr. Turner was best known for discovering Anna Mae Bullock, a teenage singer from Nutbush, Tenn., whom he renamed Tina Turner. The Ike and Tina Turner Revue made a string of hits in the 1960s before the Turners broke up in 1975.

Tina Turner described the relationship as abusive in her autobiography, “I, Tina,” which was adapted for the 1993 film “What’s Love Got to Do With It?” and made Mr. Turner’s name synonymous with domestic abuse.

“I got a temper,” he admitted in 1999 in his autobiography, “Takin’ Back My Name: The Confessions of Ike Turner.” But he maintained that the film had “overstated” it.
