7. Mittal's biggest and boldest move came in 2006, when he tried to buy Arcelor, a company created through a merger of firms from Spain, France, Luxembourg and Belgium. Luxembourg-based Arcelor was at the second spot in the industry, and its C.E.O., Guy Dollé, rejected Mittal's initial offer of $24 billion. But due to shareholder uproar, the Frenchman eventually sold his company to Mittal for $33.5 billion. At that time Arcelor chairman, Guy Dolle, was forced to swallow his words after dismissing Mittal Steel as a company of Indians paying with monkey money. As of today ArcelorMittal is the world's number one steel and mining company, with over 260,000 employees in more than 60 countries.
