Who's that sleeping man, you ask? Why it's Mark Kingdon, founder of the $6 billion hedge fund Kingdon Capital Management, who took home $200 million in pay last year according to Alpha magazine. Kingdon has a rep for his philanthropic work (unlike many of his peers), but you'll be happy to hear that he's spending some of his riches, too. Kingdon, wife Anla, and their two kids Jessica and Jason just got back from a family vacation to Beijing for the Olympics. From the looks of it, it was a rather exhausting vacation for the demi-billionaire and his wife. But just look at the culinary delights they had the opportunity to feast on. Bet you Phil Falcone and Dan Loeb didn't eat that dish for dinner last week! The Kingdon family vacation after the jump.

Linden Lab, which operates the Second Life virtual world, has found a new CEO: Mark Kingdon, the longtime chief of Organic, an online ad agency. A bizarre move for Linden, and seemingly for Kingdon. Sophisticated marketers, having toyed with Second Life, agree that it's a nonstarter as an advertising medium. Linden Lab makes its money from serving as a virtual central bank and a taxing authority. IBM is interested in it largely as a substitute for teleconferencing. Philip Rosedale, the founder and outgoing CEO, is a dreamy technologist, but replacing him with an adman makes no sense. An enterprise-software salesman would have made more sense.

Brooklyn-born Mark Kingdon is the founder of Kingdon Capital, a hedge fund with $5 billion in assets under management. According to Trader Monthly, he earned $100-150 million in 2007.
