CHICAGO (AP) -- George E. Johnson Sr., a pioneer in Black hair care whose multimillion-dollar business was the first Black-owned company to be listed on the American Stock Exchange, has died at age 99, according to his family. Johnson died Monday at his home in downtown Chicago. A cause of death was not released. Johnson and his late wife, Joan, started Johnson Products in 1954 on Chicago's South Side after securing a $250 loan. It grew into a hair care empire catering almost exclusively to Black people, with brands like Afro Sheen and Ultra Sheen. His company was a national sponsor of the hit 1970s music and dance television show "Soul Train."
