Lee Shau Kee cofounded property developer Sun Hung Kai with Kwok Tak-Seng, the late father of Hong Kong's billionaire Kwok brothers. He started Henderson Land Development in 1976; the property giant now makes up the bulk of his wealth. In 2019, he stepped down as chairman of Henderson Land and appointed his sons, Martin and Peter, as co-chairmen. A dedicated philanthropist, he's donated more than $400 million toward education over the years. Lee grew up in a poor family that could afford to eat fish or meat only twice a month.
