One of Asia’s richest men, and a pioneer of the Macau casino industry, has died. Stanley Ho reportedly passed away at the age of 98 on May 26, according to multiple sources. He passed away at the Hong Kong Sanatorium Hospital in Hong Kong.

Ho was an integral figure in Macau becoming a gambling Mecca, leading SJM Holdings to be a powerhouse in the industry. At its peak, his gambling empire was reportedly paying half of the tax receipts earned by Macau. He’s estimated to have been worth $6 billion at the time of his passing.

The continued operation of that gambling empire isn’t at risk with his passing; he passed along the responsibility to others long ago. He leaves behind 4 “wives” and 16 known children. His daughter, Daisy Ho Chiu Fung, is the current Chairman and Executive Director of SJM.

Stanley stepped away from SJM in June 2018, giving up control as many had started to worry that his failing health might be an issue. While Daisy was put in control at the time, Pansy Ho has at times battled her for the family’s casino empire.
