His death comes just two days after the nine-year anniversary of his son Michael Jackson.

Joe Jackson is credited for his role in shaping the successful careers of his children, specifically Michael Jackson and the creation of the Jackson 5 (comprised of Michael, Jackie, Tito, Jermaine and Marlon). He also played a heavy influence in Janet, Latoya and Reebie Jackson’s careers.

Controversy swirled around Jackson in his later years when he revealed to Oprah Winfrey in a 2010 interview that he admitted hitting his children with a strap.

“I don’t [regret the beatings],” he told her. “It kept them out of jail and kept them right.”

Joe Jackson is survived by his wife Katherine, 88, and nine of his 11 children.
