According to a report by TMZ, Joe Jackson, the patriarch of the Jackson 5 has passed away at the age of 89. Born Joseph Walter Jackson, he had a tough time managing his relationships with his family and overseeing the careers of Michael and Janet Jackson. He was the prototypical stage father, employing heavy-handed tactics with both outsiders and his children, which eventually led to sometimes strained relationships with his family later in life.

“If you messed up you got hit, sometimes with a switch, sometimes with a belt,” Michael wrote in his 1988 autobiography, Moonwalk. “Dad would make me so mad at him that I’d try to get back at him and get beaten all the more.

We had a turbulent relationship,” he said, adding, “Most of the time we just rehearsed. We always rehearsed.”

Ultimately, Michael wrote of his father, “He’s still a mystery man to me and he may always be one.”

Joe Jackson is survived by Katherine Jackson, eight of his 10 children by Katherine, and one other daughter from a longtime affair; as well as 26 grandchildren and numerous great-grandchildren.
