Born October 26, 1931 in Haynes, Arkansas, died August 9, 2005 in Chicago, Illinois.
A native of Haynes, Arkansas, Williams learned to play piano as a child in Flint, Michigan after his family moved there. He started his piano career in the tough clubs and juke joints around Flint, eventually relocating to Chicago in the early 1950s. He got the nickname "Detroit Junior" for his first single "Money Tree", which was released in 1960.
In 1969 Williams began a long stint as Howlin' Wolf's piano player, a spot he held until Wolf's death in 1976. He had several albums released in the 1990s and early 2000s.
