Joe Jackson, the patriarch of the musical Jackson family and the father and sometimes manager of pop stars Michael and Janet Jackson, has died. CNN reports that Jackson died today at a Las Vegas Hospital.

No cause of death was released, but Jackson, 89, had reportedly been in poor health.

A tweet sent out Sunday on Jackson’s Twitter account said: “I have seen more sunsets than I have left to see. The sun rises when the time comes and whether you like it or not the sun sets when the time comes.”

La Toya Jackson sent out a tweet today about her father, writing: “I will always love you! You gave us strength, you made us one of the most famous families in the world. I am extremely appreciative of that, I will never forget our moments together and how you told me how much you cared. #RIP Joe Jackson.”

Joe and Katherine Jackson, who married in 1949, settled in Gary, Indiana, and had 10 children.

“With a large family to support, Joe Jackson surrendered his dreams of becoming a boxer and secured a job as a crane operator for US Steel,” CNN reports. “He and his brother Luther formed a band in the mid-1950s called The Falcons, intent on booking gigs for extra money.

“The band only lasted a few years, but Jackson had developed an ear for music and believed he had found some talent in his children. He formed The Jackson Brothers in 1963 — with sons Tito, Jackie and Jermaine — and began entering them in local talent shows. With the addition of Marlon and Michael, The Jackson 5 was born in 1966. Two years later, they signed with Motown Records.”

The group became one of the most successful R&B groups in history.
