Casino mogul Sheldon Adelson's fortune has fallen $24 billion since the beginning of 2008 as shares of his Las Vegas Sands (NYSE: LVS) have dropped 95% during the year as cost-conscious consumers stay away from luxury casinos. (His fortune has dropped even further over the past two months.)

Adelson is a colorful character, who was a consulting client of mine in the 1980s. A brash guy from the streets of Dorchester -- a tough section of Boston -- Adelson first hit it big by creating Las Vegas-based COMDEX -- what was the biggest high-tech trade show around through much of the 1980s and 1990s.

Even though COMDEX faded from prominence since then, Adelson fell in love with Las Vegas and borrowed heavily to get into the casino business. Now his company holds $10.2 billion of debt on a $2.2 billion sliver of equity, and it lost $52 million over the first nine months of the year.

With the economy tanking and credit markets skittish, it could be hard for Adelson to recover. But he's been in tougher scrapes before.
