Michael Joseph Jackson was born Aug. 29, 1958, in Gary. He was 4 years old when he began singing with his brothers — Marlon, Jermaine, Jackie and Tito — in the Jackson 5. After his early success with bubblegum soul, he struck out on his own, generating innovative, explosive, unstoppable music.

The album "Thriller" alone mixed the dark, serpentine bass and drums and synthesizer approach of "Billie Jean," the grinding Eddie Van Halen solo on "Beat It," and the hiccups and falsettos on "Wanna Be Startin' Somethin'."

The peak may have come in 1983, when Motown celebrated its 25th anniversary with an all-star televised concert and Jackson moonwalked off with the show, joining his brothers for a medley of old hits and then leaving them behind with a pointing, crouching, high-kicking, splay-footed, crotch-grabbing run through "Billie Jean."

The audience stood and roared. Jackson raised his fist.

By then he had cemented his place in pop culture. He got the plum Scarecrow role in the 1978 movie musical "The Wiz," a pop-R&B version of "The Wizard of Oz," that starred Diana Ross as Dorothy.

During production of a 1984 Pepsi commercial, Jackson's scalp sustains burns when an explosion sets his hair on fire.

He had strong follow-up albums with 1987's "Bad" and 1991's "Dangerous," but his career began to collapse in 1993 after he was accused of molesting a boy who often stayed at his home. The singer denied any wrongdoing, reached a settlement with the boy's family, reported to be $20 million, and criminal charges were never filed.

Jackson's expressed anger over the allegations on the 1995 album "HIStory," which sold more than 2.4 million copies, but by then, the popularity of Jackson's music was clearly waning, even as public fascination with his increasingly erratic behavior was growing.

Billboard magazine editorial director Bill Werde said Jackson's star power was unmatched. "The world just lost the biggest pop star in history, no matter how you cut it," Werde said. "He's literally the king of pop."

Jackson's 13 No. 1 one hits on the Billboard charts put him behind only Presley, the Beatles and Mariah Carey, Werde said.

"He was on the eve of potentially redeeming his career a little bit," he said. "People might have started to think of him again in a different light."
