Mary Wilson, one of the co-founders of The Supremes, died Monday at the age of 76, her publicist announced.
Wilson "passed away suddenly" at her Henderson, Nev., home, the singer's longtime friend and publicist Jay Schwartz said in a statement. No cause of death was given.
Wilson was a "trendsetter who broke down social, racial and gender barriers," Schwartz said in his statement.
