Warren Buffett

Chief Executive Officer, Berkshire Hathaway

The only billionaire in history to amass his fortune entirely through shrewd investing. Regards Bill Gates as a close friend. Often tied with James Crowe (Level 3) and Walter Scott, Jr (Peter Kiewit Sons'). Has recently garnered a $500 million investment for Crowe and Level 3. A notorious technophobe, his sudden entrance into the telecom sector subsequent to WorldCom's collapse is seen by some analysts as a sign that good friend Gates might be after it all - the entire Internet.
