Singer Mary Wilson, a founding member of the Supremes, was part of one of the most influential and successful music history acts; she died Monday night at age 76.

Jay Schwartz, Wilson’s publicist, said that the singer died suddenly in her home in Henderson, Nev. A cause of death was not immediately given.

Known as the “sweethearts of Motown,” the Supremes blazed a trail for Black and female artists in the 1960s rivaled by few in American music. A triumphant string of 12 No. 1 hit transformed three Black teens from Detroit — Wilson, Diana Ross, and Florence Ballard — into cultural icons recognized for their glamour, elegance, and ambition.
