Berkshire Hathaway CEO Warren Buffett delivered newspapers as a child in Nebraska before moving on to earn his master's in economics from Columbia in 1951. The legendary value-investor made his name through a near-clairvoyant knack for making smart, long-term bets on companies like Coca-Cola and American Express, amassing a fortune that stands at $65 billion. Every year 20 lucky Columbia Business School students are randomly selected to fly to Nebraska and meet the Oracle of Omaha himself.
