After earning his MBA from the University of Southern California in 1983, Glasenberg joined Marc Rich & Co. in 1984, working as a marketer in the coal and coke commodity department in his native South Africa. By the time the commodity trader was bought out by management and rebranded as Glencore in 1994, Glasenberg had risen to worldwide director of the coal and coke commodity department. Chief executive for the past decade, he recently announced a $90 billion merger with mining outfit Xstrata in February. Glasenberg will serve as deputy CEO of the new entity with a focus on commodities trading. The South Africa-born executive, who became an Australian citizen during a short stint working in Melbourne and now lives in Switzerland, is the firm's largest individual shareholder and has vowed not to sell shares in the company while he works there. After shares shed 35% of their value between Glencore's high-profile IPO and late August, Glasenberg took advantage of the dip by plowing his first dividend, a $54 million payday, right back into the company. He is a former South African race-walking champion and also represented Israel in the sport.
