Billionaire financier Kirk Kerkorian, who built Las Vegas hotels and bought and sold MGM three times, has died. He was 98.

Kerkorian died Monday night, said his investment company Tracinda Corp.

Though he shunned executive titles and avoided public appearances throughout his career, Kerkorian remained an active investor into his 90s. But he never managed his enterprises, preferring to leave operational details up to a cadre of loyal lieutenants.
