Las Vegas real estate and movie studio mogul Kirk Kerkorian died on June 15. He was 98 years old, making him the world's second oldest billionaire. Only David Rockefeller, who turned 100 in June, was older. Kerkorian's life was the stuff of movies. An eighth-grade dropout, he was once a boxer and a former World War II fighter pilot trainer. He bought a plot of land in Las Vegas in 1962 and seven years later, opened the original MGM hotel and casino after picking up the movie studio. He stepped down from the board of MGM Resorts International in 2011 but remained at the time of his death the company's largest shareholder with a 19% stake. He also owned a stake in MGM China through holding company Tracinda Corp. He was known for his colorful personal life. In 2012, he was rumored to be engaged to Joan Dangerfield (the widow of comedian Rodney Dangerfield), who celebrated his 95th birthday by organizing a flash mob. He later announced his engagement to long-time friend Lu Beard, the widow of Bill Beard, the former CEO of Beard Oil Co. In 2014, he reportedly married his long-time girlfriend Una Davis. Meanwhile, his ex-wife Lisa Bonder, former tennis pro to whom he was briefly married, had been trying to get herself appointed his guardian. Kerkorian is survived by two daughters, Tracy Kerkorian and Linda Ross Hilton Kemper, and three grandchildren.
