Tiriac, a hockey player turned tennis pro, admittedly didn't have what it took to be a top player -- he once said "I am the best tennis player who cannot play tennis" -- but had the game in the business world. When the iron curtain fell, Tiriac went onto become Romania's first billionaire. A magnate in banking and insurance and other interestes, he is the 840th richest man in the world, according to Forbes magazine's ranking of the rich.
He also was a great source for quotes, saying of his infamous Davis Cup partner Ilie Nastase with whom he is pictured here, he "does not have a brain; he has a bird fluttering around in his head."
